idk who i was talking to, maybe emily or aleksana but i was complaining about nix always copying my dotfiles to the nix store. So what happened just now is i did .dump of my nix DB, then .read into a fresh DB and it had 3 effects afaict:

1. it shrunk from 599MB to 380MB ish
2. nix GC completed no problem and it felt substantially faster on average, it wasnt randomly getting stuck
3. nix no longer copies my dotfiles every time?
