mounting a partition that's located inside a disk (cd) image

[Darin Perusich]

the Boot slice, s1 onthe cd is a 250mb UFS filesystem. there are a total 
of 6 slices on this cd, 5 UFS and 1 hsfs (High Sierra or iso9660). the 
Boot slice contains an OS image which i've compressed down to about 85mb.

i've made this image avialable for download at 
http://www.nflug.org/sol9-s1-0803.tgz. i'm going to leave this up until 
tomorrow morning.
