As people may have noticed from the commits I'm working on separating
out the all the hardcoded references to struct disklabel. I'm
separating out all the disk management layering code into distinct
pieces (slice code, disklabel, partition management).
I might make a mistake, and it could blow something up, like a
filesystem, so this is a head's up that the development tree should
be considered unstable this week.
Eventually this will allow us to implement a pluggable disklabeling
scheme (e.g. a 64 bit disklabel or GPT or something like that). I'm
just getting some low-hanging fruit out of the way to make it easier
later on. GPT looks aweful, but it isn't something I'm going to worry
about right now.
