arkane-buildbot

The Arkane Linux Buildbot is a script used to pull, index and build Arch Linux pkgbuild Git repos.

Setup

1. Create and set up builduser

Create the user account;

useradd --create-home --home-dir /var/builduser --shell /usr/bin/nologin builduser

The script is run as a normal non-privileged user, however it will require passwordless sudo access to run pacman when installing build dependencies.

We will have to set up the sudoers file to allow for this by adding the following line.

builduser	ALL=(root)	NOPASSWD: SETENV: /usr/bin/pacman

2. (Optional) Customize configuration

There are a couple of default configs included, see /etc/arkane-buildbot/ for available default configs.

Note It is best to not edit these config files for they may be overwritten if you ever update arkane-buildbot, thus it is best to create a new custom config instead

You can also create a new config file under a custom name in this location.

3. (Optional) Set custom build settings

Edit /etc/makepkg.conf with your custom build environment settings, this is what Arkane is using;

CFLAGS="-march=x86-64-v3 -mtune=generic -O2 -ftree-vectorize -pipe -fno-plt -fexceptions \
        -Wp,-D_FORTIFY_SOURCE=2 -Wformat -Werror=format-security \
        -fstack-clash-protection -fcf-protection"
CXXFLAGS="$CFLAGS -Wp,-D_GLIBCXX_ASSERTIONS"
RUSTFLAGS="-C opt-level=3 -C target-cpu=x86-64-v3"
MAKEFLAGS="-j16"

Usage

Running the program manually

# If no file provided attempts to run /etc/arkane-buildbot/default instead
arkane-buildbot [FILE]

Running using the systemd service

Note Ensure the builduser is created and properly configured, or alternatively copy/edit the service to use a custom workdir and user

Note Dashes are not valid in variables

The services takes a variable as input, provide it with the name of the config file you wish to run located in /etc/arkane-buildbot/.

systemctl start arkane-buildbot@arch_community.service
