In sysinstall, pick Fixit, then CDROM/DVD.  The default shell is
/bin/sh, but since you're on a livecd, you can switch to tcsh.

Yep.  You can also do this stuff with just boot floppies, but in this
case, you'll just get the bare minimum commands (ifconfig, mount,
restore).

Restore is file-based, so it can restore onto anything.  You can even
go from a split root/var/usr system to an all-in-one-fs setup and back.

If nothing else, pxe's fun to play with.  I've mainly just used it to
serve up pxegrub so I can boot a system where I accidentally blew away
the bootblocks or cleared the active flag on all my fdisk partitions.
