If /nix/var doesn't exist, and there's no daemon, then Lix falls back to a chroot store in the user's home directory. This behavior seemingly makes it possible to run Lix inside the derivation sandbox, as agenix does for its tests.

This could really use a regression test, and since that's going to have to be a NixOS VM test we should probably try to exercise as much of the store creation code as we can in it too
