Debian Lenny Init script

[David Post]

I have written an init script that I have tested on Debian Lenny. It
is based loosely off of Arndts script from an earlier post but with a
config file for proxy/replication and includes status and sync.

It logs to /var/log/rubyrep/<whatModeYouAreRunning>.log
configs are expected in /etc/rubyrep/rubyrep.conf

Here are the files

/etc/init.d/rubyrep

#!/bin/bash
#
# /etc/init.d/rubyrep
#
# Written by David Post
# Functions provided by this file
# * Start
# * Stop
# * Restart
# * Sync
# * Status
# Configuration for use with this script should be kept in /etc/
rubyrep/rubyrep.conf
# The only configuration that I am writing right now is proxy, conf
and rubyrep.
if [ -f /etc/rubyrep/rubyrep.conf ]
then
. /etc/rubyrep/rubyrep.conf
fi
if [ ! -n "$CONFIG" ]
then
echo "No config file specified in rubyrep.conf"
exit 1
fi
[ -r /etc/rubyrep/"$CONFIG" ] || { echo "File not found: $CONFIG";
exit 1; }
CONFIG=/etc/rubyrep/"$CONFIG"
# These are some functions to make this check if RubyRep is running
before starting it.
# This checks if it is running or not
# RUN = is it running proxy or replicate, this may be different than
the configuration file says. e.g.
# The just changed the config file
function test_running(){

/etc/rubyrep/rubyrep.conf

PROXY=0
CONFIG="sepia.conf"
RUBYREP="/opt/rubyrep-1.1.0/rubyrep"

CONFIG is assumed to be in /etc/rubyrep and has this prepended to it
in the init script.

Let me know what you think.
