... and /etc/exports.

If the cluster is for some reason unexporting stuff in /etc/exports
which it shouldn't, it's a bug.

e.g.:

If you have /mnt/clusterexport in cluster.conf as an NFS export, and you
have "/tmp" as an export in /etc/exports - and the "/tmp" export is
dissappearing, that's a bug.

If you have /mnt/clusterexport in both cluster.conf
and /etc/exports, ... that's a config problem.  Let the cluster manage
the stuff you intend to export from the cluster. =)
