target-isns recently was added to Rawhide, and will be in a future Fedora release. This add-on to LIO allows it to register with an iSNS server, which potential initiators can then query for available targets. (On Fedora, see
isns-utils for both the server, and client query tools.) This removes one of the few remaining areas that other target implementations have been ahead of LIO.
Kudos and thanks to Christophe Vu-Brugier for writing this useful program!
