Well, I have been trying to duplicate the situation using VMware (great 
program for anyone just "trying things out") and noticed that one of the 
steps for creating my vinum volumes from the FreeBSD Diary is that I have to 
"disklabel -e ad3" so that I can change the volume type to vinum. I do 
remember last night when looking at the volume types via this method that 
there was nothing in there. In other words, there was not an existing entry 
for a 4.2BSD slice to edit into a vinum type...

Should I just fake it and put one in?

Using VMware as a tool I saw the following...

# /dev/ad1c:
type: ESDI
disk: ad1s1
label:
flags:
bytes/sector: 512
sectors/track: 63
tracks/cylinder: 255
sectors/cylinder: 16065
cylinders: 254
sectors/unit: 4095630
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0		# milliseconds
track-to-track seek: 0	# milliseconds
drivedata: 0

8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  c:  4095630        0    unused        0     0       	# (Cyl.    0 - 254*)
  e:  4095630        0     vinum                    	# (Cyl.    0 - 254*)

There is not a second entry line for the slice in my system anymore. Since I 
am using the entire deidcated disk should I just duplicate the above line?

Kam.
