I honestly have not seen any larger application (enterprise/custom) which allowed real rollback. In practice it's always been "reinstall / restore from backup".

I honestly have not seen any larger application (enterprise/custom) which allowed real rollback. In practice it's always been "reinstall / restore from backup". I don't see how something as complex as an OS could have that.

Very happy NixOS user here. If I have an issue with any upgrade, I just boot my system into the previous version, and then all is well until I find time to fix anything in the new version.

Maybe it technically falls under 'restore from backup', but OpenSUSE comes configured to create BTRFS snapshots before and after every package manager operation. Since this excludes the user's home, the effect is that you can rollback an update quickly without losing any work. I think this sort of system would work well for MacOS/Windows/etc, but perhaps it would give the users a bit too much power than these companies prefer...

  btrfs is awesome. The number of times I bonked my system only to restore it back just like that. Really gives the confidence to experiment and make bold changes to your system.
