In GEOM you will only find disklabels on disks which have them. That
means that there will not be disklabels on sparc64 (unless somebody
decides to put them there for obscure reasons).
Struct disklabel is being demoted from "generic communicator of disk
geometry parameters" because it doesn't do a very good job at it:
it's 32bit. And rather than invent a new proprietry 64bit format,
we have disbanded the idea in toto, and treated the four real-life
geometry parameters individually.
mediasize
sectorsize
fwsectors
fwheads
The last two are only to be used to read/write firmware/bootstrap
compatible magic data on the disks.
