I am aware of nfsrootfs as an option in deploy, but the nfs I was talking about is a transfer_method of the transfer_overlay feature in the boot action. It is an alternative to the (seemingly default) http method, and I had thought I could use it due to my DUT not having wget or curl. I may have needed to add the nfsrootfs to my deploy to get that to work though.
But I may not have to continue attempting that method though, as I have someone looking into my DUT to see about enabling wget. Until that gets done or otherwise, I was intending on seeing if I could get that nfs to work, but it may really be that I need to add an nfsrootfs to my tftp deploy.
Best regards, Michael
