			On debian I couldn't get this to work; I found a simple init-script from RH bugzillatracker which did the trick:

			<pre>
			#!/bin/sh
			### BEGIN INIT INFO
			# Provides: tgtd
			# Required-Start: $network $syslog
			# Required-Stop: $network $syslog
			# Default-Start: 2 3 4 5
			# Default-Stop:

			# Description: iSCSI target server tgt (http://stgt.sf.net)
			### END INIT INFO

			set -e

			TGTD="/usr/sbin/tgtd"
			TGTADMIN="/usr/sbin/tgt-admin"
			DEFAULTS="/etc/default/tgt"

			# Check for daemon presence
			[ -x "$TGTD" ] \|\| exit 0

			OPTIONS=""
			MODULES=""
			# Include tgtd defaults if available
			[ -r "$DEFAULTS" ] && . "$DEFAULTS"

			# Get lsb functions
			. /lib/lsb/init-functions

			case "$1" in
			start)
			log_begin_msg "Starting iSCSI target (tgt) services..."
			start-stop-daemon --start --quiet --oknodo --exec "$TGTD" -- $OPTIONS
			[ -x "$TGTADMIN" ] && $TGTADMIN -e
			log_end_msg $?
			;;
			stop)
			log_begin_msg "Stopping iSCSI target (tgt) services..."
			start-stop-daemon --stop --quiet --oknodo --retry 2 --exec "$TGTD"
			log_end_msg $?
			;;
			restart)
			$0 stop
			sleep 1
			$0 start
			;;
			reload\|force-reload)
			log_begin_msg "Reloading iSCSI target (tgt) services..."
			start-stop-daemon --stop --signal 1 --exec "$TGTD"
			log_end_msg $?
			;;

			== Re-adding LVM based iscsi disks after reboot ==
			Requires a change in how LVM 'attaches' to disks.

			So if you've added say /dev/sdb to be a complete iscsi device and on the initiator using it as a LVM, it does not attach itself to the target on reboot.

			Edit /etc/lvm/lvm.conf and change:
			<pre>
			# By default we accept every block device:
			#filter = [ "a/.*/" ]
			# Every block device except /dev/sdb, that is.
			filter = [ "r\|/dev/sdb\|" ]
			</pre>
