Unreliable for an NFS *server*?  Because having the network be
intermittently unavailable after start should not prevent the nfs server
from talking to the local resolver, and for that resolver to try a few times
to contact the upstream DNS servers for a response.  (If the network switch
was actually taking the port back down while doing STP, and therefore the
host lost its route because the interface was down, that would be a
problem... but er, that's a broken thing for a switch to do?)
