Using schroot for years here.

Can do the same but having access to host easier and so to hw devices.

Moving it around my config is easy as having dotfiles around

99% of the time a directory with your projects is all that you need.

If you really need a "container", debootstrap + systemd-nspawn does the job and provides much better sandboxing with 10x less complexity.

You don't need Docker or Nix.
