In particular comments 2 & 3.
We could change libguestfs's guestfs_mkfs (internally) so it always
does an implicit wipefs on the filesystem. wipefs is not too onerous --
in particular I believe it only writes to a few chosen areas of the
disk. Especially considering that we're about to run mkfs anyway
which for some filesystems writes a lot of blocks.
Thoughts?
Rich.
