It doesn't resolve the master key sector overwrite bug, but otherwise
works fine.  In my tests number_of_keys=4 works reliably even with
raw slices, doesn't preclude scenario w/ beginning of slice being
overwritten by other install/OS.

The issue seems at some point (depending on master key location)
w/ number_of_keys=1 the device eventually fills up enough to
overwrite key sector(s): could be boundary condition.

To try:
- number_of_keys=2, number_of_keys=3
- fist_sector=0+x, last_sector=N-x tests
- debug: set some break points in bde when (offset == master key offset)
(other tests:)
- backup/restore key sectors, try fsck
- non-ufs use of device should reproduce, verify
