I belive I have now fully assimilated the bdevs into the cdevs in
the kernel.  This means that we have reached the day where it should
be of no consequence if you mount /dev/wd0a or /dev/rwd0a.

Vinum users: Don't do anything to your vinum configuration until
grog tells you it is OK!

To test this, take your /etc/fstab file and put a 'r' in front of
the device names, ie. change:

    /dev/ad0s1a       /       ufs     rw     1    1
to
    /dev/rad0s1a       /       ufs     rw     1    1
         ^
and reboot and see if your system feels any different.

If I don't hear reports of trouble, I will go a head with the semifinal
and final steps of the operation:

	change MAKEDEV / sysinstall to create only cdevs.

	Make the bmaj -> cmaj table static and historical and remove
	the d_bmaj field from cdevsw.
