I have the iscsi target (ietd) on my Fedora systems accessed from a initiator on my MacBook,
but didn't have the iscsi initiator on any Linux boxes, so I installed it expecting some
doci somewhere. /etc/iscsi/iscsid.conf is commented, but hardly comprehensive.
But, there is
http://linux-iscsi.sourceforge.net/iscsi.conf.5.html.
Don't know why it wasn't packaged with the Fedora rpm (iscsi-initiator-utils-6.2.0.870-1.0.fc9.x86_64).
