The Joy of Linux Theming in the Age of Bootable Containers

Interesting. Didn’t know about bootable containers.

I guess the equivalent in the NixOS world would be its impermanence module, which erases root on every reboot to keep things as stateless as possible.

I think most bootc-based systems keep /etc, /var and others. So, it is more like Nix without impermanence where you can atomically change/update/rollback your system, but keep some system state.
