Bash script for easy Gentoo Linux installation

"Easy Gentoo" is a bash script, which is basically a combination of Gentoo Handbook steps, that installs Gentoo Linux from a stage3 tarball. The overall procedure is unattended, everything is handled by script. Installation includes "localization (English, Brazilian and Turkish), kernel compilation, X server setup, desktop environment setup (Xfce)" and more. These steps are enabled or disabled according to a profile.

Profile is a simple text file which has the necessary options, settings etc. for the installation. (Profile must be named as "profile") With a proper profile, it is possible to have a basic system (without X) or a ready to use Xfce desktop with a few key strokes.

"Easy Gentoo" was tested on lots of machines with different profiles. Many successful installations were made. Hope it becomes a time-saver for you. Happy compiling!

Important Notes

Easy Gentoo doesn't do partitioning, you need to do that by yourself. It formats and mounts your selection of existing partitions.
Using a capable intallation media which has more filesystem utilities, Easy Gentoo can format, mount, configure partitions for these filesystems: "btrfs, ext2, ext3, ext4, ntfs, reiserfs, xfs"
Localization is based on your "keymap". "us" is for English, "br" is for Brazilian, "trq" and "trf" are for Turkish.
A temporary swap file with 1 GB size is created as a precaution if root partition is bigger than 8 GB
There are two install types; basic: doesn't include X,LightDM,Xfce,Alsa,NetworkManager, normal: includes X,LightDM,Xfce,Alsa,NetworkManager. Base system configuration is the same for both.
Easy Gentoo needs an ethernet connection to operate, wireless connection is not an option for now.
If the host computer is a laptop, some USE flag changes and additional package merges are made (these have nothing to do with wireless)
Stable packages are used
Based on a stage3 tarball (latest one)
CFLAGS="-march=native -O2 -pipe"
LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,--sort-common -Wl,--hash-style=gnu"

Mirrors for other users:

ftp://mirrors.linuxant.fr/distfiles.gentoo.org http://gentoo.supp.name http://portage.org.ua

Portage profile is "${arch}/13.0/ for basic install" and "${arch}/13.0/desktop for normal install"
Kernel has lots of drivers activated to help to get an error free first boot
Grub2 is used, not Grub legacy
No system logger and no cron included
A few performance and security related sysctl settings are included
sudo configuration and some aliases are included
File manager is Thunar with automount support
Login Manager is LightDM

After Using Easy Gentoo, you should check/change these

Timezone
Grub config (parameters, title)
Startup services
USE flags (default ones may not be enough for you)
Mirrors
Kernel config (it is recommended to compile a new kernel with a customized config)
Compile list (to check if your 'must have' ones are installed)

How to use

boot from an installation media (ex. Gentoo Minimal Install CD)
execute these commands:

wget https://raw.githubusercontent.com/shdcn/easygentoo/master/easygentoo

chmod +x easygentoo

create a profile in the same directory where script is placed

for more information on profile please read:

https://github.com/shdcn/easygentoo/blob/master/profile

start script:

./easygentoo

Steps for basic install

Check if necessary tools/commands are available to continue
Format partitions
Mount partitions
Check mirrors
Download and extract latest stage3 tarball and portage snapshot
Continue inside chroot
Create a temporary make.conf
Emerge portage and some tools
Create locale.gen
Update make.conf and create package.use
Do a controlled "emerge -e system"
Kernel compilation (genkernel-next) with lots of needed settings/drivers
Emerge grub2 and create grub.cfg
Create/update configuration files (localtime, keymaps, hostname, etc)
Change locale based on keymap
Change root password and create user
Update /etc/sudoers and .bashrc
Unmerge unnecessary packages and do "emerge -uDN world"

Steps for normal install

Emerge xorg-server and create xorg.conf
Emerge and configure Xfce
Emerge and configure LightDM
Configure evdev
Emerge NetworkManager
Emerge and configure Alsa

End of normal install steps

Purge unnecessary man pages etc. (localepurge)
Create a small report about whole process.
Delete temporary files that were created by script
Shutdown computer

easygentoo's Issues

Passing mountpoint options on fstab

hello,

I, usually, do this when installing gentoo:

# create partitions
sgdisk -Z /dev/vda
sgdisk -o /dev/vda
sgdisk -n 1::+3M -t 1:ef02 /dev/vda
sgdisk -n 2::+500M -t 2:8300 /dev/vda
sgdisk -n 3::+512M -t 3:8200 /dev/vda
sgdisk -n 4:: -t 4:8300 /dev/vda

# create filesystems
mkfs -t btrfs -L boot /dev/vda2
mkfs -t btrfs -L btrfsroot /dev/vda4
mkswap /dev/vda3

# create subvols
mkdir /mnt/gentoo
mount /dev/vda4 /mnt/gentoo
cd /mnt/gentoo
btrfs subvol create root
btrfs subvol create home
btrfs subvol create srv
btrfs subvol create var

# unmount
cd ..
umount gentoo

This creates /dev/vda4 with subvolumes; in which I put stuff. My fstab looks like this:

# <fs>          <mountpoint>    <type>  <opts>                                              <dump/pass>

shm             /dev/shm        tmpfs   nodev,nosuid,noexec                                 0 0

/dev/vda4       /               btrfs   rw,noatime,compress=lzo,autodefrag,subvol=root      0 0
/dev/vda4       /home           btrfs   rw,noatime,compress=lzo,autodefrag,subvol=home      0 0
/dev/vda4       /srv            btrfs   rw,noatime,compress=lzo,autodefrag,subvol=srv       0 0
/dev/vda4       /var            btrfs   rw,noatime,compress=lzo,autodefrag,subvol=var       0 0
/dev/vda3       none            swap    sw                                                  0 0
/dev/vda2       /boot           btrfs   rw,noatime                                          0 0

Is there a way to pass arguments to the partition section so I can add the subvol=whatever to my profile?

Compilation failed on VMWare Workstation 10

Hi,

I've started your script on my laptop (HP Pavilion dv9744) and VMWare Workstation 10.0.3, but it failed with the following message :

Installation failed due to compile error. Package: sys-fs/udev-216. Easygentoo will exit now.

Here's the snapshot of the screen : screenshot

If I chroot and try to manually emerge this package I get this : screenshot

Hmm, looks like systemd is blocking udev, but why
does it try to install then? More details at : systemd page.

How should I proceed? Btw excellent work, really saves my time.

Download Function Date - Broken.

Get an error when script tries to download tarball - apparently there is a mismatch between the date the download function uses and the tarball date. Manually entered name of tarball (stage3-amd64-20140508.tar.bz2" in the line:

lnk="${tarballurl}/${date}/stage3-amd64-20140508.tar.bz2"; arg="1"

and it functions correctly.

Messages for package sys-apps/systemd-226-r2:
This package will overwrite one or more files that may belong to other
packages (see list below). You can use a command such as `portageq
owners / ` to identify the installed package that owns a
file. If portageq reports that only one package owns a file then do
NOT file a bug report. A bug report is only useful if it identifies at
least two or more packages that are known to install the same file(s).
If a collision occurs and you can not explain where the file came from
then you should simply ignore the collision since there is not enough
information to determine if a real problem exists. Please do NOT file
a bug report at http://bugs.gentoo.org unless you report exactly which
two packages install the same file(s). See
http://wiki.gentoo.org/wiki/Knowledge_Base:Blockers for tips on how to
solve the problem. And once again, please do NOT file a bug report
unless you have completely understood the above message.
