Is "schnapps" based on openSUSE's "snapper"?

As I’m an openSUSE contributor, inquiring minds want to know. :wink: At least the snapshot list is similar:

Turris:

# schnapps list

My system (openSUSE Tumbleweed):

It’s not. Schnapps is simple shell script while snapper is quite complex beast. Check source code:

Schnapps seems like an incredible useful tool… I wish other GNU/Linux distros would offer a similarly simplistic and at the same time user-friendly utility to keep track of system states.

Unfortunately the link to the source code is dead… where was it moved to?

It is on gitlab: https://gitlab.labs.nic.cz/turris/schnapps

You might be interested in NixOS. The rollback system has a different approach, independent of btrfs, choosable in grub. EDIT: note that the whole distro is very different from usual distros, which does have inherent disadvantages, etc. (Disclaimer: I’m a major contributor so I can’t be really impartial.)
