ghost imaging CD

[William Bierman]

Hello.  I should say first that I've tried searching for an answer to
my problem, with no success.

I am attempting to create a bootable CD with a live FreeBSD system on
it, for the purposes of installing a ghost image on a local hard
drive, retreived from a remote share (I'm using samba, if it matters),
and make that image bootable.

I have succesfully created the CD, partitioned the hard drive using
the process described in the bsdlabel manpage, and I have succesfully
installed a label on ad0s1, to get ad0s1a-f the size I wish them to
be.  I have also succesfully performed newfs on each of them, and
extracted the images (in the form of a tgz) to each slice.

My problem is this: when the machine boots, it gets to the stage:

Mounting root from "ufs:ad0s1a"

and it freezes.

Can anyone offer some insight as to why this might be happening?  If
more information is needed, I can certainly provide it, though I have
included everything I see as relevant.

Thanks!

William
