I really hope ~NixOS lives up to the standards when I try it out. I feel so dirty and fragmented when I look at all my server configurations. It has gotten better over time by using git for as much as possible but I can't track every configuration in git or even which programs I installed. Seems like that's exactly what NixOS is meant for? No more worries about you forgetting some configuration that is not persistent across boots so you don't even want to reboot a server?

I mentioned this before somewhere on SN (but can't find it right now) but I really hope NixOS is like git but for operating systems.
