I don't know about Fedora rescue disks, but on Redhat 9 disks it was
possible to not have the root filesystem mounted by the rescue system
automaticly. See if there is one for the Fedora disks.

After the lvm-mod module is successfully loaded, you have to issue the
"vgscan" command to detect the volume groups. It should say something
like "volume group VG00 found". Then you have to run "vgchange -ay" to
activate the volume group. That should create the /dev/VG00/... files
and directories for you automaticly.
