Personally I’m not super into the idea of immutable Distros, they kind of feel like Phone or Game console operating systems due to being read-only and containerized.
I prefer being able to change stuff without it being overwritten in the next update which is one of my many complaints with the steam deck and it’s immutable OS, the system is locked to read-only and even if you unlock it it’ll get relocked and all your changes undone at the next update.
