I&#x27;ve no experience with Nix, but I tried guix package manager and it was fine.  I didn&#x27;t hit any edge cases, but I didn&#x27;t dive deep.  I tried installing GuixSD (the OS) too, but failed, and because I was in a hurry, couldn&#x27;t investigate much.  But I did hit a critical issue: scarse docs.  It&#x27;s nowhere near FreeBSD where docs indeed help you out without a google search.
