# authors dsbg, franklin and abe, last modification 2009.06.08
# Copyright ETH Zurich Physics Department
# use under either modified/non-advertising BSD or GPL license
# this init.d script is intended to be run from rc2.d
# on our site it needs to run after rc2.d/S20inetd (and so identd)
# else our config file server will disallow requests for config files
# on our site it needs to run before rc2.d/S24dphys-admin
# else that will not find its /etc/dphys-admin.list config file
# so we run it as rc2.d/S22dphys-config
### BEGIN INIT INFO
# Provides: dphys-config
# Required-Start: $syslog $remote_fs
# Required-Stop: $syslog $remote_fs
# Should-Start: $local_fs
# Should-Stop: $local_fs
# Default-Start: 2 3 4 5
# Default-Stop:
# Short-Description: Fetch and merge config files, run scripts when they change
# Description: Tool to get a list of config files, and for each file
# in that list retrieve it from same server and install
# it if not yet there.
