Funtoo Linux Installation

Introduction

This document was written to help you install Funtoo Linux as concisely as possible, with a minimum number of distracting options regarding system configuration.

These docs assume you have a "PC compatible" computer system with a standard PC BIOS. Many new computers support UEFI for booting, which is a new firmware interface that frequently replaces the older MBR-based BIOS. If you have a system with UEFI, you will want to use this documentation along with the UEFI Install Guide, which will augment these instructions and explain how to get your system to boot. You may need to change your PC BIOS settings to enable or disable UEFI booting. The UEFI Install Guide has more information on this, and steps on how to determine if your system supports UEFI.

We also offer a ZFS Install Guide, which augment the instructions on this page for those who want to install Funtoo Linux on ZFS. If you are installing Funtoo Linux on ARM architecture, please see Funtoo Linux Installation on ARM for notable differences regarding ARM support. An experimental Funtoo Linux build also exists for SPARC platforms. See Funtoo Linux Installation on SPARC.

New F2FS Install Guide is in progress which will augment the instructions on this page for those who want to install Funtoo Linux on F2FS.

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.

Installation Overview

This is a basic overview of the Funtoo installation process:

Download and boot the live CD of your choice.
Prepare your disk.
Create and mount filesystems.
Install the Funtoo stage tarball of your choice.
Chroot into your new system.
Download the Portage tree.
Configure your system and network.
Install a kernel.
Install a bootloader.
Complete final steps.
Reboot and enjoy.

Live CD

Funtoo doesn't provide an "official" Funtoo Live CD, but there are plenty of good ones out there to choose from. A great choice is the Gentoo-based System Rescue CD as it contains lots of tools and utilities and supports both 32-bit and 64-bit systems. For a generation 2 Hyper-V system, the Ubuntu desktop install DVD as of version 14.04.1 works well enough. Gentoo CDs don't support EFI boot, and the System Rescue CD lacks appropriate graphics support for Hyper-V as of version 4.4.0.

It is also possible to install Funtoo Linux using many other Linux-based live CDs. Generally, any modern bootable Linux live CD or live USB media will work. See requirements for an overview of what the Live Media must provide to allow a problem-free install of Funtoo Linux.

To begin a Funtoo Linux installation, download System Rescue CD from:

http://build.funtoo.org - Master mirror
http://ftp.osuosl.org/pub/funtoo - US Funtoo Linux Mirror
http://ftp.heanet.ie/mirrors/funtoo -European Funtoo Linux mirror

Or, use your preferred live media. Insert it into your disc drive, and boot from it. If using an older version of System Rescue CD, be sure to select the rescue64 kernel at the boot menu if you are installing a 64-bit system. By default, System Rescue CD used to boot in 32-bit mode though the latest version attempts to automatically detect 64-bit processors.

Downloading the Portage tree

Note

For an alternative way to do this, see Installing Portage From Snapshot.

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 emerge --sync from within the chroot. This will automatically clone the portage tree from GitHub:

(chroot) # emerge --sync

Important

If you receive the error with initial emerge --sync due to git protocol restrictions, change SYNC variable in /etc/make.conf:

SYNC="https://github.com/funtoo/ports-2012.git"

Prepare Disk

Funtoo Linux stage3's include a pre-built debian-sources kernel to make installation faster and easier. To see what kernel version is pre-installed, type:

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

*  sys-kernel/debian-sources
      Latest version available: 5.9.6_p1
      Latest version installed: 5.9.6_p1
      Size of files: 118,723 kB
      Homepage:      https://packages.debian.org/unstable/kernel/
      Description:   Debian Sources (and optional binary kernel)
      License:       GPL-2

Firmware

At this point it is wise to emerge the 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 is not available. If using the stage3 image, perform the following to install it. linux-firmware will be already installed if using the gnome or other desktop images:

chroot # emerge -av linux-firmware

</translate>

Installing a Bootloader

Note

An alternate boot loader called extlinux can be used instead of GRUB if you desire. See the extlinux Guide for information on how to do this.

Installing Grub

The boot loader is responsible for loading the kernel from disk when your computer boots. For new installations, GRUB 2 and Funtoo's boot-update tool should be used as a boot loader. GRUB supports both GPT/GUID and legacy MBR partitioning schemes.

To use this recommended boot method, first emerge boot-update. This will also cause grub-2 to be merged, since it is a dependency of boot-update. (You may need to adjust GRUB_PLATFORMS if you are on a UEFI system. See UEFI Install Guide).

(chroot) # emerge boot-update

Then, edit /etc/boot.conf and specify "Funtoo Linux genkernel" as the default setting at the top of the file, replacing "Funtoo Linux".

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

boot {
        generate grub
        default "Funtoo Linux genkernel"
        timeout 3 
}

"Funtoo Linux" {
        kernel bzImage[-v]
        # params += nomodeset
}

"Funtoo Linux genkernel" {
# if you use bliss-kernel package
# you should change string
# kernel kernel[-v]
# to
# kernel kernel/[-v]/kernel[-v]
        kernel kernel[-v]
        initrd initramfs[-v]
        params += real_root=auto 
        # params += nomodeset
}

If you use bliss-kernel, your /etc/boot.conf should look like:

boot {
        generate grub
        default "Funtoo Linux genkernel"
        timeout 3 
}

"Funtoo Linux" {
        kernel bzImage[-v]
        # params += nomodeset
}

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

Please read man boot.conf for further details.

Running grub-install and boot-update

Finally, we will need to actually install the GRUB boot loader to your disk, and also run boot-update which will generate your boot loader configuration file:

(chroot) # grub-install --no-floppy /dev/sda
(chroot) # boot-update

Now you need to update your boot loader configuration file:

(chroot) # boot-update

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, so your changes are applied on next boot.

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

Note

If using the gnome or other desktop install image, linux-firmware and NetworkManager are already installed and available. You can use nmtui to get Wi-Fi going if you need network connectivity prior to getting X and GNOME fully up and running. In addition, desktop stage3's have ZeroConf/Bonjour multicast DNS lookups enabled by default. Both these things will not be set up yet if you are using the basic stage3 image.

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 if you have not done so already:

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:

chroot # nmtui

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

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 the supported option for network configuration, and they have their own documentation. 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

Hostnames can be up to 63 characters long and may use the following characters: a-z, 0-9 and hyphens (-). However, the hyphen may not be the first or last character.

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 -l 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.

Funtoo profiles are used to define defaults for Portage specific to your needs. There are 4 basic profile types: arch, build, flavor, and mix-ins:

arch: typically 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.
build: defines whether your system is a current, stable or experimental build. current systems will have newer packages unmasked than stable systems.
flavor: defines the general type of system, such as server or desktop, and will set default USE flags appropriate for your needs.
mix-ins: define 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.

Remember that profiles can often be inherited. For example, the desktop flavor inherits the workstation flavor settings, which in turn inherits the X and audio mix-ins. You can view this by using eselect:

(chroot) # eselect profile show
Currently set profiles:
    arch: gentoo:funtoo/1.0/linux-gnu/arch/x86-64bit
   build: gentoo:funtoo/1.0/linux-gnu/build/current
  flavor: gentoo:funtoo/1.0/linux-gnu/flavor/desktop
 mix-ins: gentoo:funtoo/1.0/linux-gnu/mix-ins/kde

Automatically enabled profiles:
 mix-ins: gentoo:funtoo/1.0/linux-gnu/mix-ins/print
 mix-ins: gentoo:funtoo/1.0/linux-gnu/mix-ins/X
 mix-ins: gentoo:funtoo/1.0/linux-gnu/mix-ins/audio
 mix-ins: gentoo:funtoo/1.0/linux-gnu/mix-ins/dvd
 mix-ins: gentoo:funtoo/1.0/linux-gnu/mix-ins/media
 mix-ins: gentoo:funtoo/1.0/linux-gnu/mix-ins/console-extras

To view installed profiles:

(chroot) # eselect profile list

To change the profile flavor:

(chroot) # eselect profile set-flavor 7

To add a mix-in:

(chroot) # eselect profile add 10
