Is it possible to get python-daemon to create "systemd style" PID file?
I.e., systemd wants a daemon to write a file with a specific name that
*contains* the PID of the child process. python-daemon, OTOH, seems to
use its pidfile parameter as more of a lock file.
Currently, I'm creating my PID file manually in the child process, but
systemd complains, because it wants the PID file to exist before the
parent exits.
I know my library, pandaemonium [1], will allow you to write the pid file complete with the daemon's PID, and I would be
very surprised if Ben's python-daemon did not also allow that.
Maybe it's just a timing issue -- have you tried having the parent process wait a few seconds to verify the file has
been created and has the PID before exiting?
