This guide draws heavily on Raspberry_Pi_2
What you need
- Raspberry PI 4
- An existing Linux install Undead_USB_Install built with fchroot is a solid choice if you do not have funtoo installed on a hard drive.
- A suitable SD card for your PI.
- An HDMI cable
- A USB keyboard
- A cat 5 network cable to connect the PI to your router
Prepare your SD card
List the device to be partitioned, mine is on /dev/sdc
root # lsblk -o name,size,label,partlabel
root # gdisk /dev/sdc
Command: o ↵ This option deletes all partitions and creates a new protective MBR. Proceed? (Y/N): y ↵
Command: n ↵ Partition Number: 1 ↵ First sector: ↵ Last sector: +1M ↵ Hex Code: EF02 ↵ Command: c ↵ Partition number: 1 Enter name: BIOS Boot
Command: n ↵ Partition Number: 2 ↵ First sector: ↵ Last sector: +128M ↵ Hex Code: EF00 ↵ Command: c ↵ Partition number: 2 Enter name: BOOT
Command: n ↵ Partition Number: 3 ↵ First sector: ↵ Last sector: ↵ Hex Code: ↵ Command: c ↵ Partition number: 3 Enter name: FUNTOO
Command: w ↵ Do you want to proceed? (Y/N): Y ↵
Create File Systems
Next, we need to create file systems on the partitions:
root # mkfs.vfat -F 32 /dev/sdc2 root # fatlabel /dev/sdc2 "BOOT" root # mkfs.ext4 /dev/sdc3 root # e2label /dev/sdc3 "FUNTOO"
Prepare Your Boot Partition
Make mount points for your boot and root partitions on the SD card:
root # mkdir /mnt/funtoo
Mount your SD card:
root # mount /dev/sdc3 /mnt/funtoo root # mkdir /mnt/funtoo/boot root # mount /dev/sdc2 /mnt/funtoo/boot
Get the Funtoo Files Onto the SD Card
Download the Necessary Files
The next step is to get the kernel, and boot firmware for the Raspberry Pi 4 from funtoo.
root # cd /mnt/funtoo root # wget https://code.funtoo.org/bitbucket/users/pnoecker/repos/666/commits/60afaf321f09988fe531d2695627ba9521666b2a#pi-boot.tar.gz root # tar -xf pi-boot.tar.gz
Grab the stage 3 files and latest portage snapshot: Subarches
root # wget https://build.funtoo.org/1.4-release-std/arm-64bit/arm64_generic/2020-09-07/stage3-arm64_generic-1.4-release-std-2020-09-07.tar.xz
Next you need to get the Funtoo files onto the root partion of the rpi.
Extract the stage 3 files to your rpi root partition:
root # tar xf stage3*
Edit your make.conf file to enable fchroot to compile:
Edit your fstab file so everything mounts correctly on boot:
root # nano /mnt/funtoo/etc/fstab
proc /proc proc defaults 0 0 LABEL=BOOT /boot vfat noauto,noatime 1 2 LABEL=FUNTOO / ext4 noatime 0 1
Chrooting into your new installation
for a good time install Package:Fchroot
First, copy the newly installed file qemu-arm to the Raspberry Pi's filesystem:
root # cp -v /usr/bin/qemu-arm /mnt/funtoo/usr/bin/ root # cp -v /usr/bin/qemu-aarch64 /mnt/funtoo/usr/bin/
Next, as root, start the binfmt service:
root # /etc/init.d/binfmt restart
Finally perform the usually chroot routine (as described in detail in the Funtoo Linux Installation Guide):
root # cd /mnt/funtoo root # mount --rbind /run run root # fchroot .
- Set yo password
root # passwd && emerge -avuND @world
At this point, it is advised to perform a world update. This will spare you some headache later on. Furthermore, to enable ssh login, don't forget to adjust the sshd_config to your needs.
Make sure all buffers have been flushed and unmount the temp directories:
root # exit root # cd .. && sync root # umount -lR funtoo
You could remove the directories and files you've used during the install if you want, but it's probably a good idea to leave them there just in case something isn't working right and you need to come back and check/reconfigure things on the SD card.
Booting the Raspberry Pi 2
Now for the fun part!
Insert the SD card into Rpi. Connect your keyboard, monitor and network card, then power it on. It should boot into Funtoo very quickly. If it doesn't work, go back through the guide and make sure you've got everything configured correctly - in particular the cmdline.txt file on the boot partition.
Log in using the password you created earlier. The first thing you'll want to do is fix the clock, set your time zone and sync your portage tree.
Because the Raspberry Pi does not have a hardware clock, you'll need to set the date and time right away. Later on we'll make sure we can get the correct time at boot via NTP, but for now we need to do it manually
root # date MMDDHHMMCCYY
Next, set your timezone:
root # ln -sf /usr/share/zoneinfo/YOURTIMEZONE /etc/localtime
Now we need make sure we can connect to the internet:
root # rc-update add dhcpcd default root # rc
The next step is to initialise our portage tree so we can start installing additional packages to our system (the emerge --sync is optional):
root # cd /usr/portage root # git checkout funtoo.org root # emerge --sync
Set your profile with epro:
Depending on what you'll be using your RPi2 for, use epro to set your profile:
root # epro subarch armv7a_hardfp root # epro flavor server
Now is a good time to enable swclock NTP so we can be sure to set the correct time the next time we boot:
root # emerge -av chrony
Once this finishes building, use rc-update to add it to the default run-level, and start the service with rc:
root # rc-update add chronyd default root # rc root # rc-update add swclock boot
Since the RPi2 doesn't have a hardware clock, remove the hwclock startup script from bootup:
root # rc-update del hwclock boot
Now you can follow the Funtoo Install documentation to continue configuring your system. You'll definitely want to look into sys-devel/distcc if you are going to be adding lots of software to your system.
