> I wanted to suggest that you adopt a mechanism which the CERN httpd
> server has for restarting it, which does not involve the user having
> to grovel around for the file containing the pid of the process:
> 
> With CERN you  can just do:
> 
> /usr/local/bin/httpd  -restart
> 
> I.e., if the -restart arg is passed to a new instance of the program,
> the new process just reads its existing pid file and sends the
> appropriate restart signal to the old process, and then dies.
> 
> This way ,the user does not need to know where the pidfile lives, they
> simply need to remember, at most where, the server config directory is.
> i.e,
> 
>  /usr/local/bin/httpd  -r /path/to/config_dir  -restart
