# zdev-root-update
#   Ensure that the persistent root device configuration is put into effect.
#   On typical distributions this requires a rebuild of the initial ram disk
#   and the re-installation of the IPL record referencing the ram disk.
#
#   Parameters:
#     zdev-root-update <devtype> <devid> [<devtype2> <devid2>...]
#
#     Where <devtype> is the device type as used by chzdev and <devid> is the
#     ID of the root device.
