so the number of blocks one must reserve for zfs boot has gone from 34
to 40.  is one supposed to, one at a time, drop each disk out of the
pool, repartition, re-add, and resilver?  luckily, there are only 16
drives, and resilvering a drive only takes a couple of days.  so we
might be done with it this calendar year.  and what is the likelihood we
make it through this without some sort of disaster?

clue bat, please?
