unit now. Don't pretend wedges have "partitions".
- Fix a buglet related to opening char and block devices of a wedge
at the same time.
- Add dkwedge_set_bootwedge(), that MD code can call to set booted_device
and booted_wedge appropriately when MD code knows the parent disk and
the start/size of the wedge that was booted from.
disklabels nested inside an MBR "NetBSD" or "386BSD" partition (first
one found is considered authoritative for the disk), or in one of several
known locations for various NetBSD platforms. It can read native or other-
endian disklabels (code is there, but not tested).
If you want to play with this, exercise caution; you can't currently
mountroot on a wedge (setroot() needs some work). Enabled by the
DKWEDGE_METHOD_BSDLABEL kernel option.
