NFS Debugging

Note: This note was originally in the Network Booting a Raspberry Pi 3 from an Ubuntu Server post.

Initially when trying to understand whether the Pi was booting from the network or not it was useful to enable NFS debugging with rpcdebug -m nfsd -s proc which reports quite verbosely to syslog.

Do disable run rpcdebug -m nfsd -c

Watching the file-system can also be helpful.
