Hmm, that's an issue that was previously only known to me for RAID devices (see
CAVEATS, first item, in the setup-storage man page).

Cool, to be honest, I didn't know about wipefs before :-)

Me too, I really like that idea. I'll try to build that wipefs call into
setup-storage, but don't know whether I'll manage today. Indeed this would also
solve the problem listed in CAVEATS, which would be really nice.
