I've been looking into what it would take to allow non-admins to boot from volume. It looks like they'd need to update a node's storage_interface; and if you'd like to boot from an iSCSI volume, then you also need to update a node's capabilities property.

Are these fields that we want non-admins to be able to update? If not, is there an alternative that might be possible?

Thanks,
