Thanks to lighten things up. I haven't tried the Restart option yet, wanted to get the basics running first. But supporting Restart is probably a good idea and a good reason to get the pid stuff right. > How about having 1 process as the interface to systemd and that > process is forking it self as the "old" and "new" processes (as you > have named)? Yes, this would be a possibility. I already thought about this, but it adds some complexity to the whole setup as I'd have to rearrange the reload logic - the new process can't start before the old one is dead. Also I'd have to forward all the console output to get error messages transfered. So this is plan B if I can't get the pid update to work.
