3. Using the GTK+ based Gentoo Linux Installer
Before you begin
Once the Gentoo Linux Installer (GLI) has finished loading, you will be greeted
by the welcome screen. It provides a friendly introduction to the process of
installing Gentoo on your computer. Remember to read each option carefully.
There is detailed help available for each step of installation; just look to the
left of each screen. We recommend that you always read the help pages before
making your choices. Note that at any time during the installation process, you
can save your configuration progress in case you need to resume your
installation at a later time.
There are three types of installation modes available. Choose Networkless
to begin installing Gentoo Linux.
Selecting Networkless will make some later configuration options
Preparing the disks
In order to install Gentoo on your machine, you will need to prepare your
disks. The Partitioning screen will show you a list of detected disks and
allow you to specify the filesystems you would like to have on your
partitions. Clicking Clear partitions will erase all previous partitions on
your disk, so be careful with this option! It is also possible to resize
certain partition types.
If you choose to go with the Recommended layout, the installer will erase
any previous partitions on your disk and create three partitions: 100MB for
/boot, a /swap partition up to 512MB in size, and the
rest of the available space on the disk is used for /, the root
As with any partitioning application, you should backup your system before
making changes to your partition table, as any possible bugs could cause data
loss. Any changes you make to your partition table will be performed by the
3.c. Network Mounts
Optional: Define network mounts
This screen lets you set up and use any existing network mounts during and after
installation. Click New to begin configuration. At this time, only NFS is
Since you are performing a GRP/networkless install, you will not be allowed
to select USE flags before installation. However, you are free to set your own
USE flags in /etc/make.conf after you have rebooted into your
You should, however, select your processor type in the CFLAGS section along
with any custom optimizations you may want, such as -O2 and
Any other options you wish to set for future use should be selected now.
Build binary packages creates ready-to-install binary tarballs of all
packages you compile on your system. DistCC allows you to share the
burden of compiling with another computer via your network connection.
You will not be allowed to change your CHOST, as this can seriously damage
your installation. In MAKEOPTS you define how many parallel compilations
should occur when you install a package. A good choice is the number of CPUs
in your system plus one, but this guideline isn't always perfect. On a
uniprocessor system, -j2 might be used.
Choose your timezone
Study the map and select the region closest to your actual location. Later,
you will be asked to select if you want your clock to be set to UTC or local
3.f. Kernel Sources
Using the LiveCD kernel
You must use the kernel present on the LiveCD for the GRP/networkless install.
This is merely a gentoo-sources kernel compiled by genkernel,
Gentoo's automated kernel compilation utility and will give you a kernel that
automatically detects and configures your hardware upon boot.
On this screen, you will be able to configure the various network interface
devices on your computer. Read the available options carefully.
On the Hostname/Proxy Information/Other tab, you will need to choose a
hostname for your machine. You may also specify proxy server and DNS settings
Cron daemons are helpful programs that run tasks at scheduled times. While you
do not need to install one, they can be quite useful. Since this is a
Networkless installation, you are limited to vixie-cron or no cron
A system logger is a necessity for any Linux operating system. Since this is a
Networkless installation, you are limited to syslog-ng or no logger.
This screen allows to you choose your bootloader and, optionally, specify
additional kernel parameters that will be used at bootup. Since this is a
Networkless installation, you are limited to grub or no bootloader.
You may specify which disk to boot from by choosing the appropriate option
from Boot Drive. In Linux, the first IDE disk in your system is called
hda, the second IDE disk is hdb, and so on. If you have SATA or
SCSI disks, they will be called sda, sdb, etc. Please make the
correct selection for your system.
If you need to pass any additional options to the kernel, such as video and/or
VGA statements, simply add them to the "Extra kernel parameters" section.
If you jumpered your harddrive because the BIOS can't handle large harddrives
you'll need to append hdx=stroke. If you have SCSI devices, you should
add doscsi as a kernel option.
Adding users and groups
First set the root password for the system administrator (the root
We strongly recommend that you create a regular user for daily work.
Working as root all the time is dangerous and should be avoided! Create
your users, add them to the appropriate groups, and set their passwords. You
can optionally change their home directories, select their login shell, and
set helpful comments.
3.k. Extra Packages
Optional: installing extra packages
The LiveCD contains a number of available pre-built packages. If you wish to
install any of them, check the appropriate box.
3.l. Startup Services
This screen allows you to choose various services to load at system boot.
Study the available options and their descriptions carefully, and then select
your desired services. For example, if you have chosen to install
xorg-x11 and want to boot straight into a graphical desktop, then you
would select "xdm" from the list.
3.m. Other Settings
Now you will be able to change various settings, including keyboard layout,
graphical display manager, the default editor, and whether to set your
hardware clock to UTC or local time.
3.n. Finishing Up
At this point, you're done. You can reboot into your new Gentoo system at any
