### BEGIN INIT INFO
# Provides: distributed-net
# Required-Start: $remote_fs
# Required-Stop: $remote_fs
# Should-Start: $network
# Should-Stop: $network
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Start the distributed.net client at boot time.
# Description: Execute the distributed.net client as a background daemon during boot
# and provide an interface for controlling it which is consistent with
# other system services.
### END INIT INFO
#
# Notes:
# - distributed.net does not like to play nicely with init scripts. It needs to be run
# without the -quiet option. Otherwise it will detach from the shell and there will
# be no way to determine its PID.
#
# This script was originally written by: Noel@debian.org, 2001-12-16.
