should have explained that my fs accepts 3 partition
layouts.
p(h0)x.y where x <= y and y <= 100.
partition by percentage. y% of the disk starting at x.
p(h0)w.z where z > 100
partition by block offsets. w-z blocks of the disk
ph0"name"
use fdisk/prep partition offsets. useable space
is up to two blocks less than one would expect
since kenfs always does RBUFSIZE-aligned io.
i'd love to get rid of the first two. the first one is
impractical since very large disks make the math very
fuzzy and the second makes mistakes easy. in either
case, the difference of one sector can be fatal.
