Danny,

Thanks for the link.  This was actually the first link we tried to get
working and after it failed to work we followed the link on the page
to http://people.freebsd.org/~rse/mirror/.

Everything worked fine until we arrived at this step below.  
# mount /dev/mirror/gm0s1a /mnt

It seems that gmirror does not give us any partitions.  A listing of
the mirror directory shows only the gm0 node even though da0 is
partitioned.  When mounting the mirror it seems that /dev/mirror/gm0
only represents the root partition.  How can we get the mirror to
recognise the other partitions?

Thanks
Chris
