Hi,

on a freshly cvsupped source tree, i notice that picobsd images
with a preloaded MD_ROOT cannot boot anymore: the kernel goes up
to this stage:

	Mounting root from ufs:/dev/md0c
	setrootbyname failed
	ffs_mountroot: can't find rootvp
	Root mount failed: 6

	Manual root filesystem specification:
	  <fstype>:<device>  Mount <device> using filesystem <fstype>
			       eg. ufs:da0s1a
	  ?                  List valid disk boot devices
	  <empty line>       Abort manual input

	mountroot>

at which point you can proceed by specifying "ufs:md0" as the root
path, and everything works fine.
It certainly used to work (though i do not remember if the root path
came out as md0c or just md0) up to a couple of months ago, roughly.

Does this ring any bell on what might have changed more or less recently
that affects this ? Who builds up the '/dev/md0c' name for the root
filesystem ?

	thanks
	luigi
