Having been booting from SAN and not always loving it, wondering how others feel about iSCSI boot in 2.0? To me this is a game changer. WAY EASIER.
Is anyone doing it? Feedback?

I've set it up for one customer and found it much harder to get working than FC boot, although it has worked perfectly since it was set up and now I know how to set it up would find it easier in future. The official documentation on getting it up and running is poor, although there is a very useful document posted in the documents section of the forum that does help. There is also a good guide in the partner website.
One major limitation is that you cannot use iSCSI boot when your service profiles are bound to a template as the iqn initiator value is not pooled. I will not be considering iSCSI boot for upcoming designs until this is resolved, although a change is planned I hear.
vSphere 5 is also not currently supported with iSCSI boot.
FInally there is a known issue listed in the release notes saying that the secondary iSCSI vnic cannot be used. Possibly a single point of failure concern.
So all in all, iSCSI boot is a welcome enhancement for me but still needs a bit of work to make it reay for prime time.

Needing to make a new boot profile for each iSCSI Target would be a pita. But might just be the reality of it. Wonder if new Boot Profiles with unique targets could be added by CLI? Maybe could create in batches.
