Since the server will be running in sync mode, the timing would be 
completely controlled by the agent.

Even if we use symlinks, we should give direct read access to the file. 
So, teams can access both the symlink and the file. Therefore, we can 
creates symlinks as a convenience and teams should either access the 
original file or be careful to not delete the symlink.
