protocols script partially failed re-creating NFS on 4.1

Just upgraded a customer cluster to 4.1. After the upgrade I tried to restore the NFS cluster.
It created the interface group & client group fine, but did not create the exports.
Output from command was:

`# ./protocols --restore localhost_28022023-091609.cfg

It took a minute or so for the NFS containers to become ready, not sure if this is some kind of timing issue ? As it thought the interface group was inactive ?
There was no SMB - so ignore that.

This looks to be a duplicate of problem #93
