Also I noticed that we always blow away all the exports and apply exports again on HUP. There are some pathological examples where automounter is involved and even though there were no changes we still going through the motions of applying exports. I thought it used to be only delta's were applied, but not anymore. Was it conscious decision, or this just needs to be fixed in the new server? Alex.
