So it’s kinda like klipper/mainsail but for an operating system?

I’ve jumped in Nix/Guix many times and always jumped back out. Sometimes you just want to edit a system file without second guessing or rebuilding the system. Same battle as initRC vs SystemD. Sometimes you just want to tinker live, because there are bigger battles elsewhere and going down a productivity sink hole of immutability is not something you can easily explain away at 3am
