That's normal, as there's no partition table on /dev/ubd0 (or let's call
it /dev/ubda, it's the same thing). You normally mount /dev/hda1,
not /dev/hda, but mount /dev/ubda, not /dev/ubda1.

Check the minor number. It should be 16, but there are around root_fs with
number 1 (which was correct when UBD didn't support partitions). This would
explain everything in your setup.
