I wonder (also see below Roger's response): Don't you add exportfs resources
to your NFS server? Then you don't need to sync the exports file.
primitive prm_nfs_XYZ_exp exportfs \
params clientspec="@XYZ_hosts" directory="/exports/XYZ" fsid=...
options="rw,..."
OK, we don't sync exportfs, but use netgroups from LDAP to define host access.
That way we don't have to adjust the cluster config when new NFS clients are
added...
