The 2004.3 livecd's now run udev. Over in bug 67886 we're running into issues on the test cd's where the udev nodes can't be saved into /lib/udev-state on shutdown since its a readonly filesystem. This breaks the shutdown on the new livecds.
Here's a quick patch which should solve this.

Don't really need this anymore since we aren't going to use the device tarball on the livecd. But I guess you might consider this anyway?

unfortunately, -w isnt all it's cracked up to be ;)

case in point ...
from a running system, do this:
# mount / -o remount,ro
# [ -w /lib/udev-state ] && echo should be ok
echo should be ok
# touch /lib/udev-state
touch: setting times of '/lib/udev-state': Read-only file system

but to satisfy the livecd peeps, we'll go with this patch:

        eend $?
-elif [ ! -e /dev/.devfsd -a -e /dev/.udev -a "${RC_DEVICE_TARBALL}" = "yes" ]
+elif [ ! -e /dev/.devfsd -a -e /dev/.udev \
+       -a "${RC_DEVICE_TARBALL}" = "yes" -a -z "${CDBOOT}" ]
 then
