Does NOT delete any files that were written to, for example, ~/.local or ~/.config from dev shell.

One of OP’s problems was,

I’m making a mess of config files and extras.

Any files created by programs running in the dev environments will remain.

NixOS containers could do what OP’s asking for, but it’ll be trickier with just nix (on other distro). It’ll handle build dependencies and such, but you’ll still need to keep your home or other directories clean some other way.

How does Tor help ssh behind NAT?

1. Not open source.
2. Can’t customise my feed in any way. It’s full of creators I don’t like who post a lot of videos.

NixOS does that well. I never quite managed to figure out a solution to this on other distros (which is actually what led me into making the jump in the end).

I want to be able to create my own if I want to. But also I think it’s important not to make everyone recreate that same work. Do it say, they should be public by default, with the option to make a private one.
