Perhaps simple vandalism?  Symlink zeod.pid to your Data.fs and the server
may overwrite it on starting up.

BTW, you may want to look at Dan Bernstein's daemontools for ideas;
they provide a framework for starting and stopping daemon processes.
(You might even consider using daemontools, but like Bernstein's other
tools the directory organization is a bit eccentric and the license
may be a problem.)  See http://cr.yp.to/daemontools.html .
