# this init.d script is intended to be run from rc2.d
#   must run after S20oidentd, else no identd answers, package server blocks us
#     preferably after basic system functions are working, such as S23ntp
#   and sensibly before lots more stuff, which wastes time if this reboots
#   so we run it as rc2.d/S24dphys-admin
