problem starting local services from nfs-mounted /usr/local

[Joseph Mingrone]

/etc/rc.conf
------------

rc_debug="YES"
rc_info="YES"

munged_enable="YES"
slurmd_enable="YES"

/etc/fstab
-----------

master:/usr/local /usr/local nfs async,rw 0 0

Once the system is up, munge and slurmd aren't running.  I don't see any
mention of them in /var/log/messages or /var/log/console.log (which I've
turned on).

# service munged start and # service slurmd start works fine and both
start once the system is up.

This used to work with other local services on 9.x systems, but not on
our 10.1 systems.  Can you suggest where I can start to debug this?

Thanks,

Joseph
