In the latest version of knfsd the semantic of /etc/exports
does not work as before. The NFS export of filesystems
across mounting points does not work.
For instance, if we have a filesytem with a partition for
root (/) one for /usr and another for /home, the export of
root / does not export /usr and /home, namely the /usr and
/home directory in the mounted filesystem will result empty.
Furthermore, trying to export the subdirectories explicitely
(/usr, /home) will results in strange behavior and crash of
I believe the semantics of /etc/exports are the same now as with BSD.
That is nfs mounts may not spread across partitions.
The mount points need to be exported explicitly.
