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 <code>/etc/fstab</code>. The others are optional. Here are a list of files that you should consider editing:

Beginning in November 2008, Intel launched the first Core i7 processor, codenamed [[Wikipedia:Bloomfield_(microprocessor)|Bloomfield]], based on the [[Wikipedia:Nehalem_(microarchitecture)|Nehalem]] microarchitecture. With this launch, they also added to and modified the conventions used in their [[Wikipedia:Intel_Core|Intel Core]] branding scheme. '''(Not to be confused with the [[Wikipedia:Intel Core (microarchitecture)|Intel Core microarchitecture]]. See [[core2_64]].)'''. This new naming scheme distinguishes between grades of processors rather than microarchitectures or design. Therefore, the '''corei7''' subarch supports the [[Wikipedia:Nehalem_(microarchitecture)|Nehalem]], [[Wikipedia:Westmere_(microarchitecture)|Westmere]], [[Wikipedia:Sandy_Bridge_(microarchitecture)|Sandy Bridge]],  [[Wikipedia:Ivy_Bridge_(microarchitecture)|Ivy Bridge]], and [[Wikipedia:Haswell_(microarchitecture)|Haswell]] microarchitectures under the following brand names:

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. (See [[#Community portal|Community]])

* Intel Core i3 (entry-level consumer)

* Intel Core i5 (mainstream consumer)
 +
* Intel Core i7 (high-end consumer/business)
 +
* Intel Xeon (business server/workstation)
  
Let's go ahead and see what we have to do. Use <code>nano -w <name_of_file></code> to edit files -- the "<code>-w</code>" disables word-wrapping, which is handy when editing configuration files. You can copy and paste from the examples.

{{fancywarning|It's important to edit your <code>/etc/fstab</code> 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 <code>gdisk</code> or <code>fdisk</code>. Skipping this step may prevent Funtoo Linux from booting successfully.}}
+
 
+
==== /etc/fstab ====
+
 
+
<code>/etc/fstab</code> is used by the <code>mount</code> command which is ran when your system boots. Statements of this file inform <code>mount</code> about partitions to be mounted and how they are mounted. In order for the system to boot properly, you must edit <code>/etc/fstab</code> and ensure that it reflects the partition configuration you used earlier:
+
 
+
<console>
+
(chroot) # ##i##nano -w /etc/fstab
+
</console>
+
 
+
You can use arrow keys to move around and hit Control-X to exit. If you want to save your changes, type "<code>Y</code>" when asked if you want to save the modified buffer, or hit Control-O before closing <code>nano</code>. Otherwise your changes will be discarded.
+
 
+
<pre>
+
# 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
+
</pre>
+
 
+
==== /etc/localtime ====
+
 
+
<code>/etc/localtime</code> 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 <code>/etc/localtime</code> with a symbolic link to the timezone that you wish to use.
+
 
+
<console>
+
(chroot) # ##i##ln -sf /usr/share/zoneinfo/MST7MDT /etc/localtime
+
</console>
+
 
+
The above sets the timezone to Mountain Standard Time (with daylight savings). Type <code>ls /usr/share/zoneinfo</code> to see what timezones are available. There are also sub-directories containing timezones described by location.
+
 
+
==== /etc/make.conf ====
+
 
+
MAKEOPTS can be used to define how many parallel compilations should occur when you compile a package, which can speed up compilation significantly. A rule of thumb is the number of CPUs (or CPU threads) in your system plus one. If for example you have a dual core processor without [[wikipedia:Hyper-threading|hyper-threading]], then you would set MAKEOPTS to 3:
+
 
+
<pre>
+
MAKEOPTS="-j3"
+
</pre>
+
 
+
If you are unsure about how many processors/threads you have then use nproc to help you.
+
<console>
+
(chroot) # ##i##nproc
+
16
+
</console>
+
 
+
Set MAKEOPTS to this number plus one:
+
 
+
<pre>
+
MAKEOPTS="-j17"
+
</pre>
+
 
+
USE flags define what functionality is enabled when packages are built. It is not recommended to add a lot of them during installation; you should wait until you have a working, bootable system before changing your USE flags. A USE flag prefixed with a minus ("<code>-</code>") 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 [http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?part=2&chap=2 Gentoo Handbook].
+
 
+
LINGUAS tells Portage which local language to compile the system and applications in (those who use LINGUAS variable like OpenOffice). It is not usually necessary to set this if you use English. If you want another language such as French (fr) or German (de), set LINGUAS appropriately:
+
 
+
<pre>
+
LINGUAS="fr"
+
</pre>
+
 
+
==== /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.
+
<console>
+
(chroot) # ##i##nano -w /etc/conf.d/hwclock
+
</console>
+
 
+
==== 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]].

Do you want a particular build of Funtoo Linux but do not see it here? Let us know what you need, and we will likely add it for you. Create a bug report requesting the build you need. To see what options there are, see our Intel Core i7 subarch page, which has a lot of builds listed.

Detailed Description

Beginning in November 2008, Intel launched the first Core i7 processor, codenamed Bloomfield, based on the Nehalem microarchitecture. With this launch, they also added to and modified the conventions used in their Intel Core branding scheme. (Not to be confused with the Intel Core microarchitecture. See core2_64.). This new naming scheme distinguishes between grades of processors rather than microarchitectures or design. Therefore, the corei7 subarch supports the Nehalem, Westmere, Sandy Bridge, Ivy Bridge, and Haswell microarchitectures under the following brand names:

  • Intel Pentium/Celeron (low-level consumer)
  • Intel Core i3 (entry-level consumer)
  • Intel Core i5 (mainstream consumer)
  • Intel Core i7 (high-end consumer/business)
  • Intel Xeon (business server/workstation)

See the following links for a list of supported Celeron, Pentium, Nehalem, Westmere, Sandy Bridge, Ivy Bridge, and Haswell processors.
