Conary had use flags without the local system doing the builds. But in general, I think the slots thing would not require any local builds - it's just a way to specify cleanly which versions of something can be available for parallel install and which cannot. By the way, I think I started using Gentoo in 2004 or so, and back then they didn't have parallel installability, but they did have parallel availability, even without slots. They just had various versions of each package available in the same repository at the same time, and I could use the package manager to express which one I want. > To do the magic NixOS does.. we need to eject the FHS and > use a similar system.

I think we could use great tools that other distros have made instead of having to make our own just because we want to be more separate from them. > [And there > would be no magic way to move from a Fedora 33 system to Fedora-Nix- > 34 > or Fedora-Gen-34.. at which point we might as well just call the > whole > thing from scratch.] If we are going that far we might as well > rewrite > conary in python3 or rust and start from there... I agree that upgrading would be hard. Resurrecting conary for Python 3 would be awesome, I'm sad that it is just sitting there in Python 2.old not being used - it's really good. Rust is also great.
