Thanks -- both of these are inspection bugs.  I have filed there here:

Note that you can do useful things with libguestfs without necessarily
needing inspection to work.  Libguestfs will open any disk image, but
without inspection you won't be able to detect OSes in the disk image
nor map devices to mountpoints, unless you do it yourself.

The first bug (Minix) is likely quite easy to fix actually.  I suspect
that adjusting this function would do it:
