I am playing around with Fedora Silverblue and openSUSE Aeon and I really like the painless updates.
Still, my daily driver for some years now is Debian, and I have a decent setup via Ansible - everything just works for me.
My question is mostly to long term Linux users, which use Linux in a professional context and jumped from a distribution like Fedora, Ubuntu, openSUSE or Debian to NixOS, Silverblue, Aeon etc.
What is your experience? How did your workflows change on your immutable Linux distribution? Did you try immutable and went back to a more traditional distribution - why? How long are you running the immutable distribution and what issues and perks did you run into?
So complex:
// take a read-only snapshot:
btrfs sub snap -r fs snapshot
… do things on fs
// rolling back:
btrfs sub del fs # at which point you’ll lose those things you’ve done
// if you want to preserve them, just rename fs instead
btrfs sub snap snapshot fs # reinstate snapshot as a read+write fs btrfs sub del snapshot # delete the non-longer needed read-only snapshot
