Thanks for the reply, Tall Man. In a way, that was the point. My experience is really only with my home network use and with nvme information displayed by linux tools which seem to insist on the xnypz suffix on the root word nvme.
I continued reading up on the general topic overnight and it seems that in the dtb tree world, the focus is on structuring cohesion and delaying actuating instances, so I am guessing different (more general) descriptors are used. My query was whether the precise descriptor was correct as I could see other options possible, one of which had, I think, popped up elsewhere. Since I had seen other reports of difficulties in loading systems to devices, I thought it a remote possibility that a typo had crept in.
I still havent found anything definitive in my reading re the formats of the abstractions in the dt stack.
I am interested in knowing about this but I as my Armbian is up and running now, and I identified the actual issue for me was a sd card error, the pressure is off .
So, I hope this ramble was not too tedious and I do appreciate that you took the time to answer, and again, thanh you
cheers
