Sounds `Mostly Harmless'. :-)
Save one point maybe: The possibility to define reserved blocks at 
beginning and end of the partition doesn't fit that nicely into the 
latest draft version of the DiskDevice API (nor into any of the earlier 
versions ;-). In order to still being able consider a partition a 
contiguous space a disk system resides on, it would be necessary to 
report only the non-reserved blocks as the partition space. But this is 
not so nice for DriveSetup, since it won't be able to display the 
reserved parts and the user might get a wrong impression about to which 
point a partition can be moved/resized.

Since the BDiskSystem::Validate*() calls will be used to ensure, that 
the new partition position and size will be OK, this won't have any bad 
consequences (let alone the slightly incorrect visualization), though. 
I could live with that.
