Well not everything is packaged and when they aren’t it Can get more complicated to install since nixos doesn’t use the default file system layout. Another thing is that certain programs have assumptions about being able to do certain things like changing their own config files that don’t work well with the nixos way of doing things. (Looking at you fish(it works but you can’t manage your configuration for it(pretty sure?)with nix))
I had no experience in nixOS, just went to the package website, it tells you exactly what to add to each section of the config.

I haven’t tried that one but besides the package page there is the options pages that gives you the ability to define config info.

Yeah it’s been awhile since I looked at it but when I was managing my config for it with home manager it would straight up refuse to start.
