yeah. keep in mind that it is very different. But I suggested it to you because you mentioned in the post, that sometimes you get a broken system and need to start from scratch. This is where NixOS shines. You only have to copy two configuration files and you are done rebuilding your system in another computer. And it is very difficult to break the system, since you can always boot to previous configurations. I am very slowly learning it because I'm very used to Arch, but I think for some purposes, NixOS is great.
