The only thing I can see is that it tries to open /dev/tty and
fails.
 However, that's very early in the process, and it continues for a long time
 after that, so I'm not sure that is causing it to fail.  It never gets to
 trying to lookup /home/erikj, it just stops at /home.
 
 I'm a bit stumped at this point.  Maybe a packet trace of a working run of
 the same thing would be helpful for comparison? 
Hello - Meetings (... bleh)
I re-ran the test using rhel76 - same image as before, same test as
before same node as before.
I nothing in the gNFS nfs log (but I didn't enable anything verbose
there).
It worked fine to do the "su - erikj" test as we expected with gNFS.
I have attached a capture to this email. I hope it helps.
I'm starting to look through the output myself but I won't be much use
at spotting something I'm afraid.
Let me know if you see something in this working case that could be a
clue! Thank you !!!!
Erik
