[CentOS] CentOS 7, NSF, "feature"

In the last month, we've discovered a new, ahhhh, "feature" in the version
of the version of NFS with CentOS 7: on startup, if it cannot resolve a
given host, it dies. It does not continue on up, with all the other hosts
it's exporting to, and just log a message.

Is there a workaround, or a configuration, to change this "fail on
unresolved host" behaviour?
