I think this might be heading for ab cd 
Has anyone installed two instances of pfclient on the same computer? I couldn't find any pointers during a search yesterday so here am I asking.
Why, you ask? My station has been in service since 2017 using a RPi model B, and works just fine, although Jessie is a bit long in the tooth now and totally unsupported! I had a RPi 4 gathering dust so it now sports the latest headless Raspbian/Raspios (or whatever they call it this week) from the RPi foundation and is running dump1090-mutability and a RTL-SDR dongle with a temporary ground plane antenna about 15ft lower than my main antenna. My objective was for the RPi 4 to replace the old model B, and it will do that. Running a simple antenna has proven that antenna theory works, and it irons out the inevitable nulls in the vertical radiation pattern that are a product of running gain antennas such as my five halfwaves in phase collinear at the top of the mast, which temporarily nulls out low-altitude aircraft at critical altitudes just a few km away from me. The ground plane provides perfect fill for those null moments and got me thinking about leaving the old model B in service for that purpose. Then I got dangerous and decided the RPi 4 had lots of reserve energy so why not run two dongles, two instances of pfclient and two share codes on the same computer?
I'm clear on running two dongles with one instance of dump1090-mutability but foggy on how to get Debian to install a second instance of the same deb package for pfclient. Debian's dpkg has an --inst option to install to a different directory but I don't know how hostile that might be to the pfclient. Maybe I'm looking down a difficult route and there's a simple way I haven't tripped over yet. So, any advice would be appreciated. If you're new to Linux, take heart. I've only been using it for 27 years
