I'm pretty sure any vendor's iSCSI storage can handle root volumes as it's just data placed on a disk. I don't know why that logic is there. Any thoughts on how this code ended up in 4.4 and 4.4-forward (since the review request is just for master)? If that would have went out to the field, it would have rendered my plug-in completely useless.
