We plan to use iSCSI arrays over TCP/IP as the shared storage for the 
MDT. So for me it would be of course much more convenient to have the
corresponding support for that in the pre-built rpms as it saves me the 
hassle to re-compile (so much for customer demand ;-).

Also, as you can turn a disk server into an iSCSI target I would think 
that this will more and more become an option to create relatively cheap 
shared storage for the MDT.

Any chance that at least the TCP/IP iSCSI initiator stuff is set back to 
the RHEL defaults?

CONFIG_SCSI_ISCSI_ATTRS=m
CONFIG_ISCSI_TCP=m
CONFIG_SCSI_QLA_ISCSI=m

Thanks,
