[Bug 1123192] [NEW] open-iscsi removes modules on stop but should not

Public bug reported:

open-iscsi's stop script has within it the following lines:

stop() {
        stoptargets
        log_daemon_msg "Stopping iSCSI initiator service"
        start-stop-daemon --stop --quiet --signal KILL --exec $DAEMON
        rm -f $PIDFILE /lib/init/rw/sendsigs.omit.d/`basename $PIDFILE`
        modprobe -r ib_iser 2>/dev/null
        modprobe -r iscsi_tcp 2>/dev/null
        log_end_msg 0
}


The modprobe -r lines attempt to remove the relevant iscsi modules. I believe this to be a bug, because there may be other users of those modules besides open-iscsi. On an upgrade (for instance) and attempt is made to remove those modules (albeit ignoring errors), and then modprobe them back in again. However, those modules are not distributed in the open-iscsi package - they are kernel modules - and open-iscsi has no business removing them as there may be other users using them in the mean time.

I can see no reason why they are being removed at all.

A simple fix is to remove the two 'modprobe -r' lines from debian/open-
iscsi.init.
