FYI...I was able to use DBUS to talk to the FSAL. the
gsh_dbus_register_path() needs to be called after gsh_dbus_pkginit(), but
pkginit has not been done during the module_ops.init_config() or
module_ops.load() methods.
https://github.com/nfs-ganesha/nfs-ganesha/blob/next/src/MainNFSD/nfs_init.c#L566
For now, I do a one-time initialization during export_ops.lookup_path()
which is called from exports_pktinit(). If there are multiple exports, you
need additional logic as you mentioned.
