Problems with pid files

[Paul Schmehl]

I just discovered a problem with two ports that I maintain, and I need 
help figuring out how to fix it.  The ports in question are 
security/sguil-sensor and security/sguil-server.  The problem, which I 
just discovered today, is that, if both ports are installed on the same 
machine (not the normal configuration), they create a pidfile with the 
exact same name.  Therefore, only one of the two ports will run at any 
given time.

I don't understand why this is happening.  The sguil-sensor port uses an 
init file named "sensor-agent.sh" and the sguil-server port uses an init 
file named "sguild.sh".  Both init scripts have the following in them: 
check_process="${command} /bin/sh".  Both ports require special stop 
routines to get them to stop properly.

Both processes create a pid named sguild.pid.  I looked at man rc.subr, 
but I don't see how to set the pidfile rather than checking for it.  Is 
there a way to force the processes to create unique pidfile names?
