# Short-Description: recreate /dev contents and udev device node database
# Description:       This script creates a /dev tree if /dev is
# mounted as a tmpfs. In comparison to the old /dev/ with devices
# populated by the devs RPM this script will only create devices that
# are actually present in the kernel at boot time. The hotplugging
# will later fill in new device entries if devices are attached and
# remove them if devices are detached.
