Comment 0 for bug 1444992

When using fastpath install, each host is given an identical iSCSI initiator name. This does not happen with Debian install mode. The result is HW SANs that use iSCSI get confused. This is an actual customer/partner issue at present.

It would appear to be fallout of the image based approach to installation.
The /etc/iscsi/initiatorname.iscsi file contains something like:
 ## DO NOT EDIT OR REMOVE THIS FILE!
 ## If you remove this file, the iSCSI daemon will not start.
 ## If you change the InitiatorName, existing access control lists
 ## may reject this initiator. The InitiatorName must be unique
 ## for each iSCSI initiator. Do NOT duplicate iSCSI InitiatorNames.
 InitiatorName=iqn.1993-08.org.debian:01:dcafddf1c8b

That is what gets used as the initiator, and is seemingly generated at
package-install time. It needs to be re-created
uniquely per installed host.
