To my shock, https://en.wikipedia.org/wiki/Network_block_device says

so I wonder if you could use that? It's better suited to swap anyways.

No swap on nfs is strange. Mainly because as far as I can tell swap over nfs has always been a thing on bsd.

here is the openbsd manual on setting up a diskless system(note the bootparams swap line), however it picked up it's netbooting sequence from bsd which if I had to guess picked it up from sun who invented nfs. I was curious if sunos also has it and it does. I choose sunos as a sort of early snapshot of a commercial bsd system. As netbooting was an important thing to Sun I would guess swap over nfs was a day one thing. Anyone know where to go for very early manuals to confirm this?
