Title:
  open-iscsi removes modules on stop but should not

Status in “open-iscsi” package in Ubuntu:
  Confirmed

Bug description:
  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.
