Installer for archlinux written in bash script

Introduction

-----------------------------------------------------------------------------------------------------------------------------------------------------------

lemon is an installer for Arch Linux that aims to be able to clone just about any Arch installation (or install a completely fresh one!).

Both ext4 and btrfs are supported at present, and a sensible btrfs subvolume configuration is included. Btrfs can be enabled via lemon.conf.

pacman can be used to generate a list of all packages installed on any given system, which can then be used as a packagelist for lemon. AUR package support is present, and can be toggled via lemon.conf (enabled by default).

Note: Only systemd is officially supported. While it's technically possible to use other init systems with lemon, it will not configure them for you automatically. As always, YMMV.

Instructions

-----------------------------------------------------------------------------------------------------------------------------------------------------------

step 1:

clone this repository into any directory on a running Arch Linux installation ISO

git clone https://github.com/m1ndflay3r/lemon

.

step 2:

give lemon execute permissions

(note: the executable lemon, not the lemon folder)

chmod 755 /path/to/lemon/directory/lemon

.

step 3:

either manually write a packagelist with each package on its own line, or use pacman to generate a list on an existing installation (recommended).

pacman -Qqe > /path/to/lemon/directory/lists/packagelist

If you generate a packagelist from a preexisting system, you will need to manually copy it to the lists folder within lemon on the arch install iso.

Note: If you have any AUR packages installed, they will be added to the auto-generated list as well. In this case, it is highly recommended to enable both AURPACKAGELIST and RETRYASAUR in lemon.conf (both are enabled by default).

.

step 4:

create a servicelist containing every service you would like enabled during installation, with each service on its own line.

eg:

cd /path/to/lemon/directory

echo "ssh" >> lists/servicelist

echo "lightdm" >> lists/servicelist

echo "NetworkManager" >> lists/servicelist

.

step 5:

edit lemon.conf and adjust any flags you require (things like grub, refind, multilib usage, etc)

Note that there are certain behaviors that interact with eachother, for example disabling root will automatically enable non-root user regardless of its explicit setting. These interactions will only ever serve to make sure a working system is present at the end of the install.

Full information on each flag and its usage can be found in the comments inside lemon.conf.

.

step 6:

Launch lemon and begin the installation!

./path/to/lemon/directory/lemon

.

Optional: AUR packages

AUR package support exists, and can be toggled via the AURPACKAGELIST flag in lemon.conf (enabled by default).

To use this feature, create the file aurpackagelist in the same format as a regular packagelist (but using aur packages, obviously).

eg:

cd /path/to/lemon/directory/

echo "stress-ng" >> lists/aurpackagelist

echo "wine-staging-git" >> lists/aurpackagelist

.

Optional: post install scripts

Post install scripts can be added to /path/to/lemon/directory/postinstall, and will be executed at the very end of the install before exiting the chroot step.

This feature can be enabled via the POSTINSTALLSCRIPTS flag in lemon.conf.

.

Note: Only vanilla Arch Linux is officially supported. while this may work with arch-based distros such as manjaro, this is not officially supported (and will definitely require tweaking lemon.conf to prevent breakage). Your mileage may vary.

lemon's Issues

Add menu to change config options

Editing lemon.conf by hand works just fine, but isn't exactly user friendly. I want to add a menu within lemon to change opts to enabled or disabled simply and concisely without having to edit anything.

Add view + clear data to main partition menu

This exists in the additional mount menu, but not the main part menu.

Add conf option to specify partitioner

Currently the end user is locked into using fdisk for partition setup. This could easily be remedied with a config option.

Add conf option to specify how many mirrors reflector should sort

Currently, reflector mirror sorting sorts 50 mirrors. This is a good number in my opinion, but can be cumbersome on speed. This number should be easily adjustable by the end user without having to edit the script.

Todo: Unmount mounted partitions if lemon is interrupted / fails

Currently, if lemon successfully mounts partitions but fails or is interrupted at a later point, these partitions remain mounted causing lemon to fail on subsequent runs without either manually unmounting these partitions or restarting the device. This can be remedied by keeping a list of partitions mounted by lemon in a separate file in /tmp/ and having lemon check for the presence of that file on launch, unmounting mounted partitions contained within it if so.

Add conf option to specify preferred editor

Currently, lemon will default on nano if it is present and vim if it is not. This can easily be a conf option.

Implement dependency handling for AUR packages which have AUR packages as dependencies

Currently, if an AUR package has non-official packages as dependencies, it will simply fail. This is, naturally, not ideal. This also impacts aurtool.

Add support for init systems besides systemd

This one is self explanatory. Even though systemd probably covers about 90% of all installs, some of you hipster edgelords like to deviate for one reason or another.

Todo: check if drive exists in formatter

Currently the formatter trusts the user to be correct. If the user happens to make a typo and not notice it (eg, typing /dev/sdaa1 instead of /dev/sda1) it will proceed without checking and fail.

AUR package installer cannot write to log

Bizzare issue that popped up as of the newer arch install isos. Even with sudo, the unprivileged user used to install aur packages is unable to write to the log due to permission denied. Attempted to work around by having aur installer write to a local log in /home/aur, then have lemonaid copy its contents to the main log if present. Didn't work. Bash is angry with me and I've come to believe I've personally angered Brian Fox.
