When curtin starts, it wants to find existing filesystems and devices, and then
be able to wipe them so as to not interfere later.

If we don't have zfs module, we won't be able to clear it; That may
be OK but could impact data not meant to be wiped.

Further, if after rebooting into the target OS, if zfs module loads there
it could impact the storage configuration.

Replace bcache or md with zfs and you know we've seen situations where
these devices take over due to hidden metadata found later.

I suspect there's no bug here in curtin or maas images; possibly
out-of-date images
on the maas node?
