Hi!
So (pseudo-code following)
if (host(NFS_server) == host(NFS_client))
rmdir(mountpoint);
ln -s export_dir mountpoint
else
makedir(mountpoint);
mount(NFS_Server:export_dir, mountpoint)
?
Now when som program does a "cd mountpoint" and the NFS Server would move to
another host, you'd have to kill all processes that use mountpoint to be able
to unmount it.
In contrast with the NFS solution, the client applications would be blocked
until NFS server is running on the other node. Obviously this solution seems
preferrable.
