I think the right answer for all this complexity is to add proper
socket activation to the various daemons NFS needs. Then the ordering
problems go away, and the services are automatically started when they
are needed, but not before. 

inetd back in the day had socket activation for RPC services, maybe we
should reintroduce that concept back to systemd?

(I didn't follow the details of this thread, my NFS-fu is a bit too
limited. If there's anything unresolved I am supposed to say something
about, please let me know.)
