IMO we should instead comment out this function (and the now-unreachable
call to it in `volume_resize`, or more specifically, everything after
the new `die` in the affected if-branch).
This *is* easily fixed by removing the `-q` from the command - the logic
otherwise works AFAICT, but we don't need this code right now anyway.
