I have mentioned now that this is Linux STGT target and that it comes
in the scsi-target-utils package.

Maybe add an example for Solaris too?
I don't use Solaris myself so I dont know how to configure iSCSI
target on Solaris.

Does OpenSolaris come with the same iSCSI target as Real-Solaris? If
so I could set it up in a VM and
try to figure out what a Solaris example could look like.


IMHO, examples are useful to get people up and running real quick to
get to a point where one they start experimenting.
straight away without having to search/learn lots of stuff first.

I know, I am completely hopless with 'git-send-email' :-)
