{{/Chroot}}
To install Funtoo Linux, the {{c|chroot}} command is first used. The chroot command will "switch into" the new Funtoo Linux system, so the commands you execute after running "chroot" will run within your newly-extracted Funtoo Linux system.
 
<!--T:114-->
Before chrooting, there are a few things that need to be done to set up the chroot environment. You will need to mount {{f|/proc}}, {{f|/sys}} and {{f|/dev}} inside your new system. Use the following commands to do so:</translate>
{{console|body=
# ##i##cd /mnt/funtoo
# ##i##mount -t proc none proc
# ##i##mount --rbind /sys sys
# ##i##mount --rbind /dev dev
}}<translate>
<!--T:115-->
You'll also want to copy over {{f|resolv.conf}} in order to have proper resolution of Internet hostnames from inside the chroot:</translate>
{{console|body=
# ##i##cp /etc/resolv.conf /mnt/funtoo/etc/
}}<translate>
<!--T:116-->
Now you can chroot into your new system. Use <code>env</code> before <code>chroot</code> to ensure that no environment settings from the installation media are pulled in to your new system:</translate>
 
{{console|body=###i## env -i HOME=/root TERM=$TERM /bin/chroot . bash -l}}
<translate><!--T:117-->
{{Note|For users of live CDs with 64-bit kernels installing 32-bit systems: Some software may use {{c|uname -r}} to check whether the system is 32 or 64-bit. You may want to append linux32 to the chroot command as a workaround, but it's generally not needed.}}
{{Important|If you receive the error "{{c|chroot: failed to run command `/bin/bash': Exec format error}}", it is most likely because you are running a 32-bit kernel and trying to execute 64-bit code. Make sure that you have selected the proper type of kernel when booting SystemRescueCD.}}
 
<!--T:118-->
It's also a good idea to change the default command prompt while inside the chroot. This will avoid confusion if you have to change terminals. Use this command:
{{console|body=# ##i##export PS1="(chroot) $PS1"}}
Test internet name resolution from within the chroot:
{{console|body=###i## ping -c 5 google.com}}
If you can't ping, make sure {{f|/etc/resolv.conf}} doesn't contain things like {{c|127.0.x.x}} addresses, if it does, change the {{c|127.0.x.x}} entry to {{c|8.8.8.8}} -- Google's public dns address.  Make sure to replace this with your dns of choice once the system is installed.
 
 
Congratulations! You are now chrooted inside a Funtoo Linux system. Now it's time to get Funtoo Linux properly configured so that Funtoo Linux will start successfully, without any manual assistance, when your system is restarted.

Introduction

This document was written to help you install Funtoo Linux on PC-compatible systems, while keeping distracting options regarding system configuration to a minimum.

If you've had previous experience installing Gentoo Linux then a lot of steps will be familiar, but you should still read through as there are a few differences. If you're new to installing a Gentoo-based Linux, or new to Linux entirely -- welcome! We have attempted to make these installation instructions understandable to new users as well.

   Note

If you are installing Funtoo Linux on ARM architecture, please see Funtoo Linux Installation on ARM for notable differences regarding ARM support.

Installation Overview

This is a basic overview of the Funtoo installation process:

  1. Download and boot the live CD of your choice.
  2. Prepare your disk.
  3. Create and mount filesystems.
  4. Install the Funtoo stage tarball of your choice.
  5. Chroot into your new system.
  6. Download the Portage tree.
  7. Configure your system and network.
  8. Install a kernel.
  9. Install a bootloader.
  10. Complete final steps.
  11. Reboot and enjoy.

Download LiveCD

In order to install Funtoo Linux, you will first need to boot your computer using a Linux-based image. This image is called a "LiveCD" for historical reasons, because historically people booted into Linux on new systems by burning an ISO image to a CD or DVD using a CD/DVD writer. This is still possible to do, if you prefer to use this method. However, most people these days will tend to use USB flash media (aka a "USB stick") for convenience, which can be written to using the standard dd command.

When installing Funtoo Linux on x86-64bit, we highly recommend the official Funtoo Linux LiveCD/LiveUSB, which can always be downloaded here:

While any modern bootable Linux image should be sufficient to install Funtoo Linux, the Funtoo LiveCD has several advantages over other options. Because it natively runs Funtoo Linux, and includes our official debian-sources kernel with very good hardware support, the hardware it supports is going to match the hardware that Funtoo Linux supports -- thus allowing you to identify any hardware compatibility issues immediately.

In addition, our LiveCD is regularly updated, and includes NetworkManager which allows the use of the easy nmtui command to configure your network. It also includes our innovative Fchroot tool, which allows you to use QEMU to "chroot" into non-x86 systems such as arm-64bit and riscv-64bit. This allows the Funtoo LiveCD to be used to even rescue and set up systems with different instruction sets!

Once downloaded, to copy it to a USB flash drive for booting, use the following command:

root # dd if=https://build.funtoo.org/livecd/funtoo-livecd-20220521-2138.iso of=/dev/sdX bs=4k status=progress oflag=sync

Of course, you will need to change /dev/sdX to point to the block device of the USB stick on your system.

Network Access

For steps on setting up network access from the LiveCD, please see the Funtoo:New Install Experience/LiveCD page.

Remote Install

Alternatively, you can log into your bootable environment over the network via SSH to perform the install from another computer, and this may be more convenient way to install Funtoo Linux.

First ensure that sshd is running. You will need to start sshd as follows:

root # /etc/init.d/sshd start

If you'd like to complete the install remotely, here's how. First, you will need to ensure that your bootable CD/USB image has a functioning network connection. Then, you will need to set a root password:

root # passwd
New password: ********
Retype new password: ********
passwd: password updated successfully


Once you have typed in a password, you will now need to determine the IP address of the bootable system, and then you can use ssh to connect to it. To determine the IP address currently being used by the LiveCD, type ifconfig:

root # ifconfig

Alternatively, determining of an IP address is possible with iproute2 ip tool:

root # ip addr show

One of the interfaces should have an IP address (listed as inet addr:) from your LAN. You can then connect remotely, from another system on your LAN, your bootable environment, and perform steps from the comfort of an existing OS. On your remote system, type the following, replacing 1.2.3.4 with the IP address of the LiveCD. Connecting from an existing Linux or MacOS system would look something like this:

remote system $ ssh root@1.2.3.4
Password: **********
   Note

If you'd like to connect remotely from an existing Microsoft Windows system, you'll need to download an SSH client for Windows, such as OpenSSH.

After you've logged in via SSH, you're now connected remotely to the LiveCD and can perform the installation steps. </translate>


Prepare Hard Disk

In this section, you will need to choose a disk format to use for booting and partitioning -- either MBR or UEFI/GPT. If you are not familiar with the differences between these options, please review our Disk Formats page for an overview of each option and the trade-offs. Generally, it's usually safe to pick the legacy MBR method for system disks under 2TB in size and most modern PC systems support MBR as well as UEFI booting.

But First...

Before doing anything to your disks, make sure you are partitioning the right one. Use the lsblk command to view a list of all block devices on your system, as well as partitions on these block devices:

root # lsblk
NAME          MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda             8:0    0  1.8T  0 disk 
├─sda1          8:1    0  512M  0 part 
├─sda2          8:2    0    8G  0 part [SWAP]
└─sda3          8:3    0  1.8T  0 part 
  ├─main-root 254:0    0  500G  0 lvm  /
  └─main-data 254:1    0  1.3T  0 lvm  /home

Make sure you will not be overwriting any important data and that you have chosen the correct /dev/sd? device. Above, you can see that sda contains three partitions, sda1, sda2 and sda3, and that sda3 contains LVM volumes.

Once you've double-checked your target block device and made sure you'll be partitioning the correct disk, proceed to the next step.

<translate>

MBR Partitioning

Legacy (BIOS/MBR) Method

   Note

Use this method if you are booting using your BIOS, and if your Funtoo LiveCD initial boot menu was light blue. If you're going to use the UEFI/GPT disk format, then please proceed to the next section.

First, it's a good idea to make sure that you've found the correct hard disk to partition. Try this command and verify that /dev/sda is the disk that you want to partition:

root # fdisk -l /dev/sda

Disk /dev/sda: 640.1 GB, 640135028736 bytes, 1250263728 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: gpt

#         Start          End    Size  Type            Name
 1         2048   1250263694  596.2G  Linux filesyste Linux filesystem

Now, it is recommended that you erase any existing MBR or GPT partition tables on the disk, which could confuse the system's BIOS at boot time. We accomplish this using sgdisk:

   Warning

This will make any existing partitions inaccessible! You are strongly cautioned and advised to backup any critical data before proceeding.

root # sgdisk --zap-all /dev/sda

Creating new GPT entries.
GPT data structures destroyed! You may now partition the disk using fdisk or
other utilities.

This output is also nothing to worry about, as the command still succeeded:

***************************************************************
Found invalid GPT and valid MBR; converting MBR to GPT format
in memory. 
***************************************************************

Now we will use fdisk to create the MBR partition table and partitions:

root # fdisk /dev/sda

Within fdisk, follow these steps:

Empty the partition table:

Command (m for help): o ↵

Create Partition 1 (boot):

Command (m for help): n ↵
Partition type (default p): 
Partition number (1-4, default 1): 
First sector: 
Last sector: +128M ↵

Create Partition 2 (swap):

Command (m for help): n ↵
Partition type (default p): 
Partition number (2-4, default 2): 
First sector: 
Last sector: +2G ↵
Command (m for help): t ↵ 
Partition number (1,2, default 2): 
Hex code (type L to list all codes): 82 ↵

Create the root partition:

Command (m for help): n ↵
Partition type (default p): 
Partition number (3,4, default 3): 
First sector: 
Last sector: 

Verify the partition table:

Command (m for help): p

Disk /dev/sda: 298.1 GiB, 320072933376 bytes, 625142448 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x82abc9a6

Device    Boot     Start       End    Blocks  Id System
/dev/sda1           2048    264191    131072  83 Linux
/dev/sda2         264192   4458495   2097152  82 Linux swap / Solaris
/dev/sda3        4458496 625142447 310341976  83 Linux

Write the partition table to disk:

Command (m for help): w

Your new MBR partition table will now be written to your system disk.

   Note

You're done with partitioning! Now, jump over to Creating filesystems.

GPT Partitioning

UEFI/GPT Method

   Note

Use this method if you are interested in booting using UEFI, and if your Funtoo LiveCD initial boot menu was black and white, or the system booted without a boot menu. If it was light blue, this method will not work. Instead, use the instructions in the previous section then skip this section, or reboot LiveCD in UEFI mode first.

   Note

You can build legacy mode into your GPT partition table but it requires a BIOS Boot partition. see Talk:Install/GPT_Partitioning

The gdisk commands to create a GPT partition table are as follows. Adapt sizes as necessary, although these defaults will work for most users. Start gdisk:

root # gdisk /dev/sda

Within gdisk, follow these steps:

Create a new empty partition table (This will erase all data on the disk when saved):

Command: o ↵
This option deletes all partitions and creates a new protective MBR.
Proceed? (Y/N): y ↵

Create Partition 1 (boot):

Command: n ↵
Partition Number: 1 ↵
First sector: 
Last sector: +128M ↵
Hex Code: EF00 ↵

Create Partition 2 (swap):

Command: n ↵
Partition Number: 2 ↵
First sector: 
Last sector: +4G ↵
Hex Code: 8200 ↵

Create Partition 3 (root):

Command: n ↵
Partition Number: 3 ↵
First sector: 
Last sector:  (for rest of disk)
Hex Code: 

Along the way, you can type "p" and hit Enter to view your current partition table. If you make a mistake, you can type "d" to delete an existing partition that you created. When you are satisfied with your partition setup, type "w" to write your configuration to disk:

Write Partition Table To Disk:

Command: w ↵
Do you want to proceed? (Y/N): Y ↵

The partition table will now be written to the disk and gdisk will close.

Now, your GPT/GUID partitions have been created, and will show up as the following block devices under Linux:

  • /dev/sda1, which will be used to hold the /boot filesystem,
  • /dev/sda2, which will be used for swap space, and
  • /dev/sda3, which will hold your root filesystem.
   Tip

You can verify that the block devices above were correctly created by running the command lsblk.

</translate>


<translate>

Creating Filesystems

   Note

This section covers both BIOS and UEFI installs. Don't skip it!

Before your newly-created partitions can be used, the block devices that were created in the previous step need to be initialized with filesystem metadata. This process is known as creating a filesystem on the block devices. After filesystems are created on the block devices, they can be mounted and used to store files.

Let's keep this simple. Are you using legacy MBR partitions? If so, let's create an ext2 filesystem on /dev/sda1:

root # mkfs.ext2 /dev/sda1

If you're using GPT partitions for UEFI, or installing for Raspberry Pi, you'll want to create a vfat filesystem on your first partition. This will be mmcblk0p1 in the case of Raspberry Pi:

root # mkfs.vfat -F 32 /dev/sda1

Now, let's create a swap partition. This partition will be used as disk-based virtual memory for your Funtoo Linux system.

You will not create a filesystem on your swap partition, since it is not used to store files. But it is necessary to initialize it using the mkswap command. Then we'll run the swapon command to make your newly-initialized swap space immediately active within the live CD environment, in case it is needed during the rest of the install process:

root # mkswap /dev/sda2
root # swapon /dev/sda2

Root Filesystem

Now, we need to create a root filesystem. This is where Funtoo Linux will live. We generally recommend ext4 or XFS root filesystems. Keep in mind that some filesystems will require additional filesystem tools to be emerged prior to rebooting. Please consult the following table for more information:

FilesystemRecommended as root file system?Additional tools required to emerge
ext4YesNone
XFSYessys-fs/xfsprogs
reiserfsYes -- will likely need to enable kernel supportsys-fs/reiserfsprogs
zfsNo - advanced users onlysys-fs/zfs
btrfsNo - advanced users onlysys-fs/btrfs-progs
   Important

We do not recommend users set up ZFS or BTRFS as their root filesystem. This is much more complex and usually not necessary. Instead, choose XFS or ext4. We do support ZFS or BTRFS as non-root filesystems and this is much, much easier to configure. See ZFS and Btrfs after you are done setting up your Funtoo Linux system to configure ZFS or BTRFS for additional secondary storage.

If you're not sure, choose ext4. Here's how to create a root ext4 filesystem:

root # mkfs.ext4 /dev/sda3

...and here's how to create an XFS root filesystem, if you prefer to use XFS instead of ext4:

root # mkfs.xfs /dev/sda3

Your filesystems (and swap) have all now been initialized, so that that can be mounted (attached to your existing directory heirarchy) and used to store files. We are ready to begin installing Funtoo Linux on these brand-new filesystems.

Additional Filesystems

   Note

This can be very useful for Raspberry Pi systems!

You may want to create additional filesystems for various parts of your Funtoo filesystem tree. It is not uncommon to place /home or /var on separate filesystems.

For Raspberry Pi, you may not have a lot of spare room on the card depending on the capacity of your microSD card, and it may make a lot of sense to put the entire /var filesystem on an external hard drive or solid state disk. This will not only ensure you don't run out of disk space, but can also improve performance since writes to the microSD card typically aren't that fast.

To do this, you will want to use fdisk or gdisk to create a partition on your external drive, and then use the mkfs.xfs or mkfs.ext4 commands to create a filesystem on the new partition. We will mount this new filesystem in the next step prior to extracting the stage3 tarball.

</translate>


<translate>

Mounting Filesystems

Mount the newly-created filesystems as follows, creating /mnt/funtoo as the installation mount point:

root # mkdir /mnt/funtoo
root # mount /dev/sda3 /mnt/funtoo
root # mkdir /mnt/funtoo/boot
root # mount /dev/sda1 /mnt/funtoo/boot

If you have any additional filesystems you created earlier (such as /home or /var), you should mount them now, so that when the stage3 is extracted (which we will do in a later step) these filesystems will get populated with the necessary files. This can be done as follows:

root # mkdir /mnt/funtoo/var
root # mount /dev/sdb1 /mnt/funtoo/var

</translate>


<translate>

Setting the Date

   Important

If your system's date and time are too far off (typically by months or years), then it may prevent Portage from properly downloading source tarballs. This is because some of our sources are downloaded via HTTPS, which use SSL certificates and are marked with an activation and expiration date. However, if your system time is relatively close to correct, you can probably skip this step for now.

Now is a good time to verify the date and time are correctly set to UTC. Use the date command to verify the date and time:

root # date
Fri Jul 15 19:47:18 UTC 2011

If the date and/or time need to be corrected, do so using date MMDDhhmmYYYY, keeping in mind hhmm are in 24-hour format. The example below changes the date and time to "July 16th, 2011 @ 8:00PM" UTC:

root # date 071620002011
Fri Jul 16 20:00:00 UTC 2011

Once you have set the system clock, it's a very good idea to copy the time to the hardware clock, so it persists across reboots:

root # hwclock --systohc

</translate>


<translate>

Download and Extract Stage3

Now that filesystems are created and your hardware and system clock are set, the next step is downloading the initial Stage 3 tarball. The Stage 3 is a pre-compiled system used as a starting point to install Funtoo Linux.

To download the correct build of Funtoo Linux for your system, first familiarize yourself with the Support Matrix, in particular the Desktop Environments section, to help you make a decision about which desktop environment to set up (we recommend GNOME for new users.) Then, head over to the Subarches page. Subarches are builds of Funtoo Linux that are designed to run on a particular type of CPU, to offer the best possible performance. They also take advantage of the instruction sets available for each CPU.

What Subarch?

From the subarch list at Subarches, choose your desired level of optimization. A system built specifically for your CPU will run faster than a less-optimized system. For a modern Intel or AMD system, it is safe to pick the exact optimization level for your particular family of CPU. This will offer the best possible performance.

If you are using a virtualization technology to run Funtoo Linux and your VM may be used on different types of hardware, then it's recommended that you use a stage3 that is optimized for the oldest CPU instruction set that your VM will run on, or a more generic image if it may run on both AMD and Intel processors.

Once you have found the appropriate subarch at Subarches, you will likely have a few installation images to choose from. This next section will help you understand which one to pick.

Which Image?

Our desktop environment stages (GNOME, Cinnamon, etc.) now support seamless installation on VMware Workstation Pro virtual machines. We highly recommend you enable 3D Accelerated Video for your VM, which is not enabled by default. Click here for more info.

You can always manually choose an installation image via https://build.funtoo.org as well as using the Subarches page. Here is some guidance on choosing the best .tar.xz image for download. When choosing an image:

Pick 1.4-release-std.
This is release 1.4 of Funtoo Linux, our current release.
Pick the subarch for the CPU family of the system you are installing on.
This will provide the best performance.
Choose stage3 for...
The stage3 is a more traditional, minimal and non-graphical installation of Funtoo. You will then build your system up to your desired state using emerge.
Choose gnome for...
The gnome installation image, if available, includes the full GNOME environment as well as Firefox already optimized for your hardware. You can then continue to further customize your system after installation. See the Desktop Environments section of our Support Matrix for more desktop options.
The lxd image for...
The lxd image is for use with LXD, and is not used for installing directly on a desktop or laptop, so you should not select this option for regular installs. To install, first download and then lxc image import <name>.tar.xz --alias funtoo and then you can lxc launch funtoo my_container.

Download the Stage3

Once you have found the stage3 that you would like to download, use wget to download the Stage 3 tarball you have chosen to use as the basis for your new Funtoo Linux system. It should be saved to the /mnt/funtoo directory as follows:

root # cd /mnt/funtoo
root # wget https://build.funtoo.org/1.4-release-std/x86-64bit/generic_64/stage3-latest.tar.xz

Verify downloaded tarball

Funtoo Linux stage tarballs are signed using GPG by the build server they are built on. It's a good practice to verify authenticity and integrity of downloaded files when possible. For instructions how to import and trust GPG keys check our wiki page about GPG signatures.

Then, you can download the stage3's GPG signature and use the gpg --verify command in order to verify your tarball:

root # wget https://build.funtoo.org/1.4-release-std/x86-64bit/generic_64/stage3-latest.tar.xz.gpg
root # gpg --verify stage3-latest.tar.xz.gpg stage3-latest.tar.xz

Once the stage is downloaded and verified, extract the contents with the following command, substituting in the actual name of your Stage 3 tarball:

root # tar --numeric-owner --xattrs --xattrs-include='*' -xpf stage3-latest.tar.xz
   Important

It is very important to use all the options included above. See below for details.

Here are what the options to tar do:

--numeric-owner
Without this option, tar will map ownership and group ownership based on the UID to user and GID to group mappings as defined on the LiveCD. We don't want this -- we want the numeric values of the UIDs and GIDs in the tarball to be preserved on disk, so when your Funtoo Linux system boots, the UIDs and GIDs are set correctly for Funtoo. That is what this option tells tar to do.
--xattrs --xattrs-include='*'
Funtoo Linux uses filesystem extended attributes to set Linux capabilities, which allow for certain programs such as ping to have enhanced privileges without having to be fully 'suid root'. Even with the -p option, tar will not restore extended attributes we need unless these two options are specified.
-xpf
This instructs tar to extract (x), preserve regular permissions and ownership (p), and use the filename (f) specified.

<translate>

Chroot into Funtoo

To set up your Funtoo Linux system, we need to "enter into" it before we boot. If you are using the Funtoo Linux LiveCD, this can be easily done with the fchroot command:

root # fchroot /mnt/funtoo /bin/bash --login
fchroot #

The fchroot command will take care of all necessary steps to enter into your new Funtoo Linux system, as well as clean up things when you exit the fchroot by typing exit or ctrl-D.

If you are using another LiveCD or USB media to install Funtoo, you can manually chroot by using the following set of commands:

root # cd /mnt/funtoo
root # mount --rbind /proc proc
root # mount --rbind /sys sys
root # mount --rbind /dev dev
root # cp /etc/resolv.conf /mnt/funtoo/etc/
root # # chroot . /bin/su --login
chroot #
   Note

For users of live CDs with 64-bit kernels installing 32-bit systems: Some software may use uname -r to check whether the system is 32 or 64-bit. You may want to append linux32 to the chroot command as a workaround, but it's generally not needed.

   Important

If you receive the error "chroot: failed to run command `/bin/bash': Exec format error", it is most likely because you are running a 32-bit kernel and trying to execute 64-bit code. Make sure that you have selected the proper type of kernel when booting your live CD.

Test internet name resolution from within the chroot:

chroot # ping -c 5 google.com

If you can't ping, make sure that /etc/resolv.conf specifies a valid IP address for a reachable nameserver in its nameserver setting.

Congratulations! You are now chrooted inside a Funtoo Linux system. Now it's time to get Funtoo Linux properly configured so that Funtoo Linux will start successfully, without any manual assistance, when your system is restarted. </translate>


Downloading the Portage tree

Now it's time to install a copy of the Portage repository, which contains package scripts (ebuilds) that tell portage how to build and install thousands of different software packages. To create the Portage repository, simply run ego sync from within the chroot. This will automatically clone the portage tree from GitHub and all kit submodules:

(chroot) # ego sync

Configuring your system

As is expected from a Linux distribution, Funtoo Linux has its share of configuration files. The one file you are absolutely required to edit in order to ensure that Funtoo Linux boots successfully is /etc/fstab. The others are optional.

Using Nano

The default editor included in the chroot environment is called nano. To edit one of the files below, run nano as follows:

(chroot) # nano -w /etc/fstab

When in the editor, you can use arrow keys to move the cursor, and common keys like backspace and delete will work as expected. To save the file, press Control-X, and answer y when prompted to save the modified buffer if you would like to save your changes.

Configuration Files

Here are a full list of files that you may want to edit, depending on your needs:

FileDo I need to change it?Description
/etc/fstab YES - required Mount points for all filesystems to be used at boot time. This file must reflect your disk partition setup. We'll guide you through modifying this file below.
/etc/localtime Maybe - recommended Your timezone, which will default to UTC if not set. This should be a symbolic link to something located under /usr/share/zoneinfo (e.g. /usr/share/zoneinfo/America/Montreal)
/etc/portage/make.conf Maybe - recommended Parameters used by gcc (compiler), portage, and make. Note that it is normal for this file to be empty in Funtoo Linux, as many settings have been migrated to our enhanced profile system.
/etc/conf.d/hostname Maybe - recommended Used to set system hostname. Set the hostname variable to the fully-qualified (with dots, ie. foo.funtoo.org) name if you have one. Otherwise, set to the local system hostname (without dots, ie. foo). Defaults to localhost if not set.
/etc/hosts No You no longer need to manually set the hostname in this file. This file is automatically generated by /etc/init.d/hostname.
/etc/conf.d/keymaps Optional Keyboard mapping configuration file (for console pseudo-terminals). Set if you have a non-US keyboard. See Funtoo Linux Localization.
/etc/conf.d/hwclock Optional How the time of the battery-backed hardware clock of the system is interpreted (UTC or local time). Linux uses the battery-backed hardware clock to initialize the system clock when the system is booted.
/etc/conf.d/modules Optional Kernel modules to load automatically at system startup. Typically not required. See Additional Kernel Resources for more info.
/etc/conf.d/consolefont Optional Allows you to specify the default console font. To apply this font, enable the consolefont service by running rc-update add consolefont.
profiles Optional Some useful portage settings that may help speed up intial configuration.

If you're installing an English version of Funtoo Linux, you're in luck, as most of the configuration files can be used as-is. If you're installing for another locale, don't worry. We will walk you through the necessary configuration steps on the Funtoo Linux Localization page, and if needed, there's always plenty of friendly, helpful support available. (See Getting Help)

Let's go ahead and see what we have to do. Use nano -w <name_of_file> to edit files -- the "-w" argument disables word-wrapping, which is handy when editing configuration files. You can copy and paste from the examples.

   Warning

It's important to edit your /etc/fstab file before you reboot! You will need to modify both the "fs" and "type" columns to match the settings for your partitions and filesystems that you created with gdisk or fdisk. Skipping this step may prevent Funtoo Linux from booting successfully.

/etc/fstab

/etc/fstab is used by the mount command which is run when your system boots. Lines in this file inform mount about filesystems to be mounted and how they should be mounted. In order for the system to boot properly, you must edit /etc/fstab and ensure that it reflects the partition configuration you used earlier in the install process. If you can't remember the partition configuration that you used earlier, the lsblk command may be of help to you:

(chroot) # nano -w /etc/fstab
   /etc/fstab - An example fstab file
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
#
# See the manpage fstab(5) for more information.
#
# <fs>	     <mountpoint>  <type>  <opts>         <dump/pass>

/dev/sda1    /boot         ext2    noauto,noatime 1 2
/dev/sda2    none          swap    sw             0 0
/dev/sda3    /             ext4    noatime        0 1
#/dev/cdrom  /mnt/cdrom    auto    noauto,ro      0 0
   Note

If you're using UEFI to boot, change the /dev/sda1 line so that it says vfat instead of ext2. Similarly, make sure that the /dev/sda3 line specifies either xfs or ext4, depending on which filesystem you chose earlier on in the installation process when you created filesystems.

/etc/localtime

/etc/localtime is used to specify the timezone that your machine is in, and defaults to UTC. If you would like your Funtoo Linux system to use local time, you should replace /etc/localtime with a symbolic link to the timezone that you wish to use.

(chroot) # ln -sf /usr/share/zoneinfo/MST7MDT /etc/localtime

The above sets the timezone to Mountain Standard Time (with daylight savings). Type ls /usr/share/zoneinfo to list available timezones. There are also sub-directories containing timezones described by location.

/etc/portage/make.conf

USE flags define what functionality is enabled when packages are built. It is not recommended to add a lot of USE flags during installation; you should wait until you have a working, bootable system before changing your USE flags. A USE flag prefixed with a minus ("-") sign tells Portage not to use the flag when compiling. A Funtoo guide to USE flags will be available in the future. For now, you can find out more information about USE flags in the Gentoo Handbook.

/etc/conf.d/hwclock

If you dual-boot with Windows, you'll need to edit this file and change the value of clock from UTC to local, because Windows will set your hardware clock to local time every time you boot Windows. Otherwise you normally wouldn't need to edit this file.

(chroot) # nano -w /etc/conf.d/hwclock

Localization

By default, Funtoo Linux is configured with Unicode (UTF-8) enabled, and for the US English locale and keyboard. If you would like to configure your system to use a non-English locale or keyboard, see Funtoo Linux Localization.

Introducing Portage

Portage, the Funtoo Linux package manager has a command called emerge which is used to build and install packages from source. It also takes care of installing all of the package's dependencies. You call emerge like this:

(chroot) # emerge packagename

When you install a package by specifying its name in the command-line, Portage records its name in the /var/lib/portage/world file. It does so because it assumes that, since you have installed it by name, you want to consider it part of your system and want to keep the package updated in the future. This is a handy feature, since when packages are being added to the world set, we can update our entire system by typing:

(chroot) # ego sync
(chroot) # emerge -auDN @world

This is the "official" way to update your Funtoo Linux system. Above, we first update our Portage tree using git to grab the latest ebuilds (scripts), and then run an emerge command to update the world set of packages. The options specified tell emerge to:

  • a - show us what will be emerged, and ask us if we want to proceed
  • u - update the packages we specify -- don't emerge them again if they are already emerged.
  • D - Consider the entire dependency tree of packages when looking for updates. In other words, do a deep update.
  • N - Update any packages that have changed (new) USE settings.

You should also consider passing --with-bdeps=y when emerging @world, at least once in a while. This will update build dependencies as well.

Of course, sometimes we want to install a package but not add it to the world file. This is often done because you only want the package installed temporarily or because you know the package in question is a dependency of another package. If this behavior is desired, you call emerge like this:

(chroot) # emerge -1 packagename

Advanced users may be interested in the Emerge wiki page.

Updating World

Certain packages in the Funtoo stage3 tarball are compiled with the bindist USE flag enabled by default. bindist flag controlling enable or disable of options for proprietary and/or patented part of code which is disallowed to distribute in images due to licensing issues.). You may notice a dependency resolution problem with bindist USE during updating packages after initial system setup. To avoid potential problems, update the system before first boot or any other package installation as shown below:

(chroot) # ego sync
(chroot) # emerge -auDN @world
   Important

Make sure you read any post emerge messages and follow their instructions. This is especially true if you have upgraded perl or python.

Kernel

Starting mid-May 2015, Funtoo Linux stage3's include a pre-built debian-sources kernel to make installation faster and easier. To see if debian-sources is installed, type:

(chroot) # emerge -s debian-sources
Searching...    
[ Results for search key : debian-sources ]
[ Applications found : 1 ]

*  sys-kernel/debian-sources
      Latest version available: 3.19.3
      Latest version installed: 3.19.3
      Size of files: 81,292 kB
      Homepage:      http://www.debian.org
      Description:   Debian Sources (and optional binary kernel)
      License:       GPL-2

If a version is listed under Latest version installed, then debian-sources is already pre-built for you and you can skip the rest of the Kernel section, and proceed to the Installing a Bootloader section.

   Important

At this point it is wise to emerge latest sys-kernel/linux-firmware package, because various drivers rely on firmware blobs and instructions. Hardware like wi-fi cards, graphic cards, network cards, and others will not work properly or at all if firmware not present.

Building the Kernel

If you need to build a kernel for Funtoo Linux, please follow these steps:

   Note

See Funtoo Linux Kernels for a full list of kernels supported in Funtoo Linux. We recommend debian-sources for new users.

   Important

debian-sources with binary USE flag requires at least 20GB free in /var/tmp and takes around 1 hour to build on a Intel Core i7 Processor.

Let's emerge our kernel:

(chroot) # emerge debian-sources

Once emerge completes, you'll have a brand new kernel and initramfs installed to /boot, plus kernel headers installed in /usr/src/linux, and you'll be ready to configure the boot loader to load these to boot your Funtoo Linux system.

   Warning

If you have a RAID in your machine, the kernel installation will pull in the mdadm tool as a dependency. It is important to edit the /etc/mdadm.conf file prior to rebooting the machine so the RAID is properly recognised and set up before the kernel attempts to mount it in the tree. Failing to do so can result in an unusable or even unbootable system! For specific details, consult the mdadm man page man mdadm or the mdadm ebuild page.

   Note

NVIDIA card users: the binary USE flag installs the Nouveau drivers which cannot be loaded at the same time as the proprietary drivers, and cannot be unloaded at runtime because of KMS. You need to blacklist it under /etc/modprobe.d/.

   Note

For an overview of other kernel options for Funtoo Linux, see Funtoo Linux Kernels. There may be modules that the Debian kernel doesn't include, a situation where genkernel would be useful. Also be sure to see hardware compatibility information.

Installing a Bootloader

These install instructions show you how to use GRUB to boot using BIOS (old-school) or UEFI (new-school). As of boot-update-1.7.2, now in Portage, the steps are very similar.

First, emerge boot-update. This will also cause grub-2 and efibootmgr to be merged, since they are dependencies:

(chroot) # emerge boot-update

Then, edit /etc/boot.conf using nano and specify "Funtoo Linux genkernel" as the default setting at the top of the file, replacing "Funtoo Linux". Also, if you're not using memtest86+ remove the entry in boot.conf to avoid errors.

/etc/boot.conf should now look like this:

   /etc/boot.conf
boot {
	generate grub
	default "Funtoo Linux genkernel" 
	timeout 3 
}

"Funtoo Linux" {
	kernel bzImage[-v]
}

"Funtoo Linux genkernel" {
	kernel kernel[-v]
	initrd initramfs[-v]
	params += real_root=auto 
} 

"Funtoo Linux better-initramfs" {
	kernel vmlinuz[-v]
	initrd /initramfs.cpio.gz
}

If you are booting a custom or non-default kernel, please read man boot.conf for information on the various options available to you.

Old School (BIOS) MBR

When using "old school" BIOS booting, run the following command to install GRUB to your MBR, and generate the /boot/grub/grub.cfg configuration file that GRUB will use for booting:

(chroot) # grub-install --target=i386-pc --no-floppy /dev/sda
(chroot) # boot-update

New School (UEFI) Boot Entry

If you're using "new school" UEFI booting, run of the following sets of commands, depending on whether you are installing a 64-bit or 32-bit system. This will add GRUB as a UEFI boot entry.

For x86-64bit systems:

(chroot) # grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id="Funtoo Linux [GRUB]" --recheck /dev/sda
(chroot) # boot-update

For x86-32bit systems:

(chroot) # grub-install --target=i386-efi --efi-directory=/boot --bootloader-id="Funtoo Linux [GRUB]" --recheck /dev/sda
(chroot) # boot-update

First Boot, and in the future...

OK -- you are almost ready to boot!

You only need to run grub-install when you first install Funtoo Linux, but you need to re-run boot-update every time you modify your /etc/boot.conf file or add new kernels to your system. This will regenerate /boot/grub/grub.cfg so that you will have new kernels available in your GRUB boot menu, the next time you reboot.

Configuring your network

It's important to ensure that you will be able to connect to your local-area network after you reboot into Funtoo Linux. There are three approaches you can use for configuring your network: NetworkManager, dhcpcd, and the Funtoo Linux Networking scripts. Here's how to choose which one to use based on the type of network you want to set up.

Wi-Fi

For laptop/mobile systems where you will be using Wi-Fi, roaming, and connecting to various networks NetworkManager is strongly recommended. Since Wi-Fi cards require firmware to operate, it is also recommended that you emerge the linux-firmware ebuild:

(chroot) # emerge linux-firmware networkmanager

Depending on your architecture, you might now see a message similar to the following:

The following USE changes are necessary to proceed
...

This means that your USE flags need to be updated to allow this installation. For now, you can let portage handle this for you by adding the flag --autounmask-write:

(chroot) # emerge linux-firmware networkmanager --autounmask-write

After this, update the config:

(chroot) # dispatch-conf

Accept the new config by pressing u. Then, you can proceed to install NetworkManager:

(chroot) # emerge linux-firmware networkmanager
(chroot) # rc-update add NetworkManager default

The above command will ensure that NetworkManager starts after you boot into Funtoo Linux. Once you've completed these installation steps and have booted into Funtoo Linux, you can use the nmtui command (which has an easy-to-use console-based interface) to configure NetworkManager so that it will connect (and automatically reconnect, after reboot) to a Wi-Fi access point:

root # nmtui

For more information about NetworkManager, see the NetworkManager package page.

   Note

wpa_supplicant is also a good choice for wireless network connections. See the net-wireless/wpa_supplicant package for steps involved in setting up wpa_supplicant.

Desktop (Wired DHCP)

For a home desktop or workstation with wired Ethernet that will use DHCP, the simplest and most effective option to enable network connectivity is to simply add dhcpcd to the default runlevel:

(chroot) # rc-update add dhcpcd default

When you reboot, dhcpcd will run in the background and manage all network interfaces and use DHCP to acquire network addresses from a DHCP server.

If your upstream DHCP server is dnsmasq, it can be configured to assign addresses via mac address to make servers on DHCP feasible.

Server (Static IP)

For servers, the Funtoo Linux Networking scripts are recommended. They are optimized for static configurations and things like virtual ethernet bridging for virtualization setups. See Funtoo Linux Networking for information on how to use Funtoo Linux's template-based network configuration system.

Hostname

By default Funtoo uses "localhost" as hostname. Although the system will work perfectly fine using this name, some ebuilds refuse to install when detecting localhost as hostname. It also may create confusion if several systems use the same hostname. Therefore, it is advised to change it to a more meaningful name. The hostname itself is arbitrary, meaning you can choose almost any combination of characters, as long as it makes sense to the system administrator. To change the hostname, edit

(chroot) # nano /etc/conf.d/hostname

Look for the line starting with hostname and change the entry between the quotes. Save the file, on the next boot Funtoo will use the new hostname.

   Warning

Do not use special characters in the hostname, as the shell may interpret these, leading to unpredictable results. Use the Latin alphabet: a-z, A-Z, 0-9

   Tip

Use short hostnames (up to 8 or 10 characters) to prevent the terminal screen being filled with the hostname, leaving little space for the command itself. This become particularly poignant when coding long command strings in various programming languages like Bash, Python, SQL and Perl

Finishing Steps

Set your root password

It's imperative that you set your root password before rebooting so that you can log in.

(chroot) # passwd

Restart your system

Now is the time to leave chroot, to unmount Funtoo Linux partitions and files and to restart your computer. When you restart, the GRUB boot loader will start, load the Linux kernel and initramfs, and your system will begin booting.

Leave the chroot, change directory to /mnt, unmount your Funtoo partitions, and reboot.

(chroot) # exit
root # cd /mnt
root # umount -lR funtoo
root # reboot
   Note

System Rescue CD will gracefully unmount your new Funtoo filesystems as part of its normal shutdown sequence.

You should now see your system reboot, the GRUB boot loader appear for a few seconds, and then see the Linux kernel and initramfs loading. After this, you should see Funtoo Linux itself start to boot, and you should be greeted with a login: prompt. Funtoo Linux has been successfully installed!

Profiles

Once you have rebooted into Funtoo Linux, you can further customize your system to your needs by using Funtoo Profiles. A quick introduction to profiles is included below -- consult the Funtoo Profiles page for more detailed information. There are five basic profile types: arch, build, subarch, flavors and mix-ins:

Sub-Profile TypeDescription
archTypically x86-32bit or x86-64bit, this defines the processor type and support of your system. This is defined when your stage was built and should not be changed.
buildDefines whether your system is a current, stable or experimental build. current systems will have newer packages unmasked than stable systems. This is defined when your stage is built and is typically not changed.
subarchDefines CPU optimizations for your system. The subarch is set at the time the stage3 is built, but can be changed later to better settings if necessary. Be sure to pick a setting that is compatible with your CPU.
flavorDefines the general type of system, such as server or desktop, and will set default USE flags appropriate for your needs.
mix-insDefines various optional settings that you may be interested in enabling.

One arch, build and flavor must be set for each Funtoo Linux system, while mix-ins are optional and you can enable more than one if desired. Often, flavors and mix-ins inherit settings from other sub-profiles. Use epro show to view your current profile settings, in addition to any inheritance information:

(chroot) #  epro show

=== Enabled Profiles: ===

        arch:  x86-64bit
