Pacha is able to run on the background with the --daemon-start flag. However, you may want to do this automatically in your environment.
Here is an example INIT script that you could use (modify to fit your needs):
#! /bin/sh
### BEGIN INIT INFO
# Provides: pacha
# Required-Start:
# Required-Stop:
# Default-Start: 2 3 4 5
# Default-Stop: 0 1
# Short-Description: Start the pacha daemon.
### END INIT INFO

Sometimes you do not need to run the daemon in the background, but rather, see what is going on as you go.
Pacha has a --daemon-foreground option that lets you do just that. It will run in the foreground and will not exit unless you send a KeyboardInterrupt (Ctrl-C in most cases).
Another option to deal with daemonization is if you do not really care for a daemon to be always in the background. To avoid this issue, we provide an option that will run all the tasks once and will exit safely at the end. The option daemon-run-once will accomplish this and it is really convenient if you want to call pacha via cron and set up a cron job that can take care of running.
Sometimes, setting up cron and calling pacha is easier than dealing with annoying daemonizing processes from the OS.
