AFAIK the intel iSCSI code on sf.net has a sample target implementation
but the last time I looked only contained target code for a ram disk and
a fake user mode disk (file on a normal file system).

A quick look through the UNH implementation
(http://sourceforge.net/projects/unh-iscsi/) suggests that their target
code can be used to export real disks.

I found this mini howto:
http://eludicate.com/~bolen/iscsi/

Suggests that root fs with the CISCO iSCSI software initiator might
work.
