fdisk wants slices to start on a head boundary, and end on a cylinder

if you make start evenly divisible by the number of sectors per track,
and make size+start evenly divisible by sectors*heads, fdisk won't
change any of the numbers on you.
So, for your disk:
start / sectors = 332775
you have size specified as 467427240, so:
(467427240 + 20964825) / (16 * 63) = 484515.9375
fdisk will treat that as 484515 and do:
(16 * 63 * 484515) - 20964825 = 467426295
and use that number as the new size.
Thanks for the explanation :)
This matches ad6. It would appear that ad4 had the start and end values
explicitly set causing it to come out with different numbers.
Gotcha. ad6 , ad8 and ad10 (*) , the ones I sliced by hand, follow this
rule. ad4 doesn't, which is the one that got created by sysinstall on
the initial setup. I told it to create a slice of 10GB.
So sysinstall doenst follow the rule? Am I missing something here?
I guess i can move all of ad4s1 around to ad6s1, boot off ad6, rebuild
ad4s1 and move back in... right?
(*) FWIW, all four drives are exactly the same, so the only difference
is how the slices were done.
