I can't figure out exactly how this patch could apply, but I can see it
or something similar being useful when using guix-home-service. If we
can make oneshot service attempt to register a new generation on every
invocation /and/ use a patch like to avoid redundant generations, it may
solve many of the issues raised in [1].
