The main thing is that all files in the store end up being written by
the guix daemon user.  So if we want the files to be easily
substitutable, they'd need to have a fixed uid/gid, and the only one we
can guarantee is root.  Other than that, it needs to use a bunch of
Linux namespaces to isolate the builds from the rest of the system,
which depending on the kernel build-time configuration might not be
possible when unprivileged.

Best,
