Bug #1547: disklabel64 automatic sizing
http://bugs.dragonflybsd.org/issues/1547#change-11794

* Author: corecode
* Status: In Progress
* Priority: Normal
* Assignee: tuxillo
* Category: Userland
* Target version: 3.8.0
----------------------------------------
disklabel64 is a prime example for unintuitive behavior:

* it requires an arbitrary 4KB aligment on sizes and offset
* size aligments seem to be enforced directly, but offset alignments are 
not.  offsets just show up as "ILLEGAL" when re-editing the label.  no 
complaint before
* automatic sizing using "*" does not work:

d: * * HAMMER

but then:
partition d: size out of bounds (4825292800)

the size is completely off, roughly by a factor of 10(!)

I had to do:

d: 4 * HAMMER

and then re-edit to make it read

d: * 4712200 HAMMER

* there is no way to change the display block size
* there is no way to specify sector counts or byte counts in size/offset
