Adding a partition

[David J. Weller-Fahy]

I left about 26GB free on my 80GB hard drive.  Having found a use for
that space, I now want to add a partition.  I've not added one by hand,
and /stand/sysinstall gives me a 'cannot write to ...' message, so I
want confirmation that what I'm about to do won't crump on me. ;]

System is two 80GB ATA hard drives on a 'Promise PDC20269 UDMA133
controller' (according to dmesg), with one on each channel (both
master).  I'm running software raid using atacontrol.

My current partition table follows:

#v+
dave[tigger]~> sudo bsdlabel ar0s1
# /dev/ar0s1:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  a:  1048576        0    4.2BSD     2048 16384     8
  b:  2097152  1048576      swap
  c: 156296322        0    unused        0     0         # "raw" part, don't edit
  d: 73400320 30408704    4.2BSD     2048 16384 28544
  e:  2097152  3145728    4.2BSD     2048 16384 28552
  f: 12582912  5242880    4.2BSD     2048 16384 28552
  g: 12582912 17825792    4.2BSD     2048 16384 28552
#v-

To use up the unused space, I believe I need to add the following line:

#v+
  h: 52487298 103809024    4.2BSD     2048 16384 28552
#v-

Could someone who's done that before confirm whether that looks right?
