Broken parted? :-P

The OmniOS equivalent "prtvtoc /dev/rdsk/c7t2d0p0" should should show
something like:
prtvtoc /dev/rdsk/c1t8d0p0                                                                                                                                            
* /dev/rdsk/c1t8d0p0 partition map
*
* Dimensions:
*     512 bytes/sector
* 27262976 sectors
* 27262909 accessible sectors
*
* Flags:
*   1: unmountable
*  10: read-only
*
* Unallocated space:
*       First     Sector    Last
*       Sector     Count    Sector 
*          34       222       255
*
*                          First     Sector    Last
* Partition  Tag  Flags    Sector     Count    Sector  Mount Directory
       0      4    00        256  27246303  27246558
       8     11    00   27246559     16384  27262942

Which is how the default ZFS partition is set. 256 sectors is a multiple of 1 and 8.
Methinks something else is going on here.
