# Nix Profile GC

Clean up old profiles more carefully than `nix-collect-garbage --delete-older-than`

This module removes most old profiles, but makes sure to keep around the last few profiles that
served this machine well -- profiles this machine ran on for a (configurable) time -- even if
they're old.

This is a NixOS Module rather than a stand-alone tool because it determines which extra profiles
need preserving by periodically logging the currently-active profiles.
