I mounted a second disk on an existing system according to the instructions
in the FAQ.  After getting an inderstanding of things better I finally got
it to format and mount but I think it did it wrong.  Here's the disklabel;

# /dev/rsd1c:
type: SCSI
disk: SCSI disk
label: fictitious
flags:
bytes/sector: 512
sectors/track: 87
tracks/cylinder: 4

7 partitions:
#        size   offset    fstype   [fsize bsize   cpg]
  a:      512      192     unknown                        # (Cyl.    0*- 2*)
  b:       10   479340     unknown                        # (Cyl. 1843*- 1843*)
  c:   479350        0      unused        0     0         # (Cyl.    0 - 1843*)
  g:   478636      704      4.2BSD        0     0     0   # (Cyl.    2*- 1843*)


I tried mounting slice g but it wouldn't format/mount.  So I tried c and it
worked (and is working).  Shouldn't 'g' be the slice that mounts?  What is
the difference?

Thanks!
