Ah, that will break /etc/init.d/halt.sh

Particularly the stuff around here:

    ebegin "Saving device nodes"
		  ...
        cd /dev
        # Find all devices
        find . -xdev -type b -or -type c -or -type l | cut -d/ -f2- > \
            "${devices_real}"
        # Figure out what udev created
        eval $(grep '^[[:space:]]*udev_db=' /etc/udev/udev.conf)
        if [[ -d ${udev_db} ]]; then
            # New udev_db is clear text ...
            udevinfo=$(cat "${udev_db}"/*)
        else
            # Old one is not ...
            udevinfo=$(udevinfo -d)
        fi
        # This basically strips 'S:' and 'N:' from the db output, and then
        # print all the nodes/symlinks udev created ...
		...

The script will be unable to figure out what device is being handled by
udev, and what is not.
