Are you saying that on a jammy system, after "sudo apt install nfs-common", you don't get rpc_pipefs mounted?

Right after installing nfs-common, I have it:

ubuntu@j-nfs:~$ mount -t rpc_pipefs
sunrpc on /run/rpc_pipefs type rpc_pipefs (rw,relatime)

And it was the generator that did it, as expected:
