I manage my personal development machine using Puppet and like to automate as many parts of the setup as I can. The setup of the machine itself is defined in workstation.pp and applied using run_puppet.sh.
OS: Ubuntu
FS: ZFS
GUI: Wayland
Window Manager: Sway
I also use Puppet to bootstrap the machine and automate as much of the Ubuntu installation as possible. The bootstrap configuration is defined in bootstrap/bootstrap.pp.
The bootstrap config is applied by booting the machine using an Ubuntu live USB stick, installing git, cloning this repository and running bootstrap/bootstrap.sh.
The bootstrap configuration is mostly copied from https://wiki.gentoo.org/wiki/User:Bugalo/Dell_XPS_15_7590 and https://wiki.gentoo.org/wiki/User:Fearedbliss/Installing_Gentoo_Linux_On_ZFS.
