yeah nix shells are awesome. I use a few suckless things to the point I have my own #suckless nix development shell. Just load that up whenever I need to change or build someting and i’m good to go. for my other dev things I just use flakes which makes it just as easy. all I have to do is CD into a project directory and then my environment is instantly setup. CD out and it’s gone. All that on top of my system config being in a repo I can reinstall my system on any PC within minutes.

Really NixOS is the end game of Linux Distros. Once you finally figure it out you’ll never distro hop again.
