This is covered by tests like “basic” and other lightweight tests: they
boot the system, so they get to exercise the file system label/UUID
lookup code (if the root partition is specified by a label/UUID at
least).

Most of the time is spent in building the latest Guix and running ‘guix
system init’.  I don’t think this can be sped up.

The QEMU images involved are copied around, and maybe that part can be
slightly optimized.  I did that in
