One last Q: why "-b 16" ? From the disklabel(8):
-b s1bno Install primary at block number s1bno instead of the default
location for the machine and file system type. [alpha, pmax,
vax]
-B s2bno When hard-coding the blocks of secondary into primary, start
from block s2bno instead of trying to determine the block
numbers occupied by secondary by examining filesystem. If
this option is supplied, secondary should refer to an actual
secondary bootstrap (rather than the file name of the one
present in filesystem) so that its size can be determined.
...just curious...
