VxFS runs on many different different platforms and uses this approach, but
I would expect a per OS not per machine type solution. I haven't given it
a tremendous amount of thought, but I assumed that it would be part of the

Don't these drivers already have to know how to find the BSD disklabel?

Last time I looked at CCD, it did. What I mean by moving my disks around
is handling situations like, "Gee, I'm not getting enough bandwidth using
only one controller here. I think I'll buy a second one and split up my
disks." After turning off the machine, sticking in the new controller and
messing with some cables, I should be able to simply power on the system
and have everything work transparently.
