These are mostly stock images that I created for my own personal use.
Intial work was forked from: [https://github.com/bsherman/ublue-custom/] (https://github.com/bsherman/ublue-custom/)

Custom uBlue image based on Team UBlue os. This is a custom version of [Fedora Silverblue] (https://fedoraproject.org/silverblue/), essentially.

Images built:

• Silverblue (Fedora GNOME immutable desktop)

Based on:

• ublue-os/main for good foundations
  • adds distrobox, freeworld mesa and media codecs, gnome-tweaks (on gnome), just, openssl, pipewire-codec-aptx, ratbagd, vim
  • sets automatic staging of updates to system
  • sets flatpaks to update at 04:00 and on start
  • v4l2loopback driver from ublue-os/akmods
  • xpadneo/xone xbox controller drivers from ublue-os/akmods
• ublue-os/nvidia for nvidia variants adds:
  • nvidia kernel drivers
  • nvidia container runtime
  • nvidia vaapi driver

Upon the first time booting and on each update, the system will check if $HOME/.config/ublue-os/firstboot/.firstboot-ran exist and if it does not it will go through a series of scripts that do things like install flatpaks and... well that is all it does at the moment. You can remove this file if you wish for it to run again on next update.

We build latest which points to Fedora 40:
