Feeling happy about the move to Debian

NixOS is probably the nicest implementation of this, yeah. If you're unfamiliar, the whole package set is just one big git repo containing all of the build scripts, with one big public cache that continuously rebuilds it. So there's not really even any "releases" per se, just one git commit hash for the whole distribution.

But you really don't need to go that esoteric to have a nice workflow like that. Pretty much all not too-big-to-fail distros have highly automated packaging that can release updates with a git push or even just a button press on an automatically created PR.

I think even in Fedora you only need to register the upstream release tarball with their internal mirror and put update it's hash in a file these days, at least when I last looked at it. And that's using the venerable RPM, not something newfangled.
