Subject: [PATCH] iSCSI: no more iscsid
According to Cathy Zhou <Cathy.Zhou@Oracle.COM>:
"iscsistart is not designed to be working together with iscsid. When an
interface gets the dhcp offer successfully, the iscsiroot script is run
which starts the iscsistart service to establish the iSCSI session. With
the existence of iscsid, the iscsistart service's attempt to setup its
own mgmt ipc fails. Instead, the request to login to the iscsi target
is handled by the mgmt ipc of iscsid. After iscsistart finishes its
login attempt, it eventually sends a stop_event_loop request to stop
the mgmt process. As the result, it terminates iscsid."
So, iscsid is kicked out again.
Additionally iscsistart-flocked is used to make sure iscsistart is not
run in parallel.
