- Add patch to make iscsiadm complain and exit when run as user instead of
hang spinning for the database lock
- Add patch to make iscsiadm start iscsid when needed (rh 436175 related)
- Don't start iscsi service when network not yet up (in case of using NM)
add NM dispatcher script to start iscsi service once network is up

# Note we should have $network in Required-Start/Stop but we don't because if
|
|
# we would require network chkconfig will put us directly after NetworkManager
|
|
# when using NM, which will make our see if the network is up test succeed
|
|
# while NM is actually still configuring the network. By not requiring network
|
|
# chkconfig will use the chkconfig header to determine our start prio, starting
|
|
# us after the old network service, but before NM (netfs does this the same).
