It’s a lot of work tbh. I’ve used arch for 10+ years and recently switched to NixOs to give it a spin, and couldn’t get my exact setup that I wanted for tools and accessories I use, and the system immutability isn’t that practical imo. So I switched back to my old Arch setup and now just use Flakes for various projects I have, basically just the Nix part, which is very nice imo.
