Hey Tomasz,

It is looking pretty good. I will have more constructive comments as I 
try it out more, but wanted to say thanks for doing this.

To distinguish between iscsi specific or other target type specific 
params do you think it would be good to do something like:


<target-type iscsi>
	
	# setting something like CHAP here would work like IET's
	# ietd.conf
	incominguser user1 secretpass12


	<target iqn.2007-04.com.example:san.monitoring>
	.....

	# would we set values like iscsi's MaxRecvDataSegmentLength here ?
	</target>

	<target iqn.2007-04.com.example:san.monitoring>
	.....
	</target>
</target-type iscsi>
