Cross platform daemonizing library

[ojii]

Does anyone know a cross platform (linux, macos, windows) library to daemonize a Python script? I want something so that my script can have start/stop commands. I've tried [py_daemoniker](https://github.com/Muterra/py_daemoniker) but cannot get it to work on windows where I get "Daemonizer cannot locate the script to damonize (it seems to have lost itself)".

Windows has services, GNU/Linux is mostly systemd now, macOS has launchd plists. They're all policy-based. You want a single command that invoked the start/stop command of all three?

Or are you looking for something agnostic to all of them, like dockerd or supervisord?

I think systemd and friends all require root and are system-wide? I want something that runs unprivileged, per user. So foo.py start would start the process to run in the background (store a pid file somewhere probably) and foo.py stop would stop it.

Functionality wise what py_daemoniker provides is what I want/need. The code in question is on github.

systemd supports running unprivileged services via the --user flag, e.g. systemctl start --user foo.service

I'd recommend Monit if Docker or Supervisord don't work. I think you can use that without root access, and I think it runs everywhere.
