Then instead of having a wiki describing a set of things to install and in which order for your hardware, you can grab a YAML from a git repository "arch-hardware" and it should work.
The next step is probably moving towards an interim step that generates a /system.yaml from a known language, DSL, or library.
Is there an immutable OS based on Debian? I want a rock solid base with the rollback functionality immutable distros give.
As I'm typing this I just remembered there's VanillaOS. Currently still in beta for 2.0 but they switched from ubuntu base to debian base. Very excited for it
Try btrfs for root partition, add snapper and you're pretty much done. Not that it will be inmutable, but you can rollback updates. Check btrfs awesome list on github (for the many other tools) and documentation..
Might be about time to try blendOS I guess. All that's missing is Gentoo-like local compilation of packages to tick all the boxes of stuff Linux people get off on.
