Ignore the previous mail. This was a different issue. I am still working
on it.
Use the attached iscsi init script instead of the one that comes with
the iscsi initiator utils.
Just drop it in
/etc/init.d/iscsi
It is the same except it has "network" in the RequiredStart section. The
problem is making it work with NM. As you can see in the comments in the
top of the script it says not to add network, because of NM. But without
it in F16 due to systemd changes from F15, it will not get run at the
right time, the network will be done and the script will not log in.

# description: Logs into iSCSI targets needed at system startup
# Note we should have $network in Required-Start/Stop but we don't because if
# we would require network chkconfig will put us directly after NetworkManager
# when using NM, which will make our see if the network is up test succeed
# while NM is actually still configuring the network. By not requiring network
# chkconfig will use the chkconfig header to determine our start prio, starting
# us after the old network service, but before NM (netfs does this the same).
