supermin didn't rebuild the appliance for some reason.  It should have
done because of this code, so I wonder why that didn't happen.

https://github.com/libguestfs/supermin/blob/4c019aedf3e6bff79746f99cb2fcba44e039d552/src/supermin.ml#L232-L251

You might try straceing supermin to see if it really does a stat on
/usr/lib/x86_64-linux-gnu/guestfs/supermin.d.

To force the appliance to rebuild you can remove /var/tmp/.guestfs-*
and run the test again.
