I ran into an issue when I upgraded my Debian unstable box to systemd. I have FreeSWITCH on this box and the systemd initiation is not working.
Dec 14 18:05:44 mail systemd[1]: freeswitch.service: Start operation timed out. Terminating.
Dec 14 18:05:48 mail systemd[1]: Failed to start freeswitch.
Dec 14 18:05:48 mail systemd[1]: freeswitch.service: Unit entered failed state.
Dec 14 18:05:48 mail systemd[1]: freeswitch.service: Failed with result 'timeout'.
Dec 14 18:05:48 mail systemd[1]: freeswitch.service: Service hold-off time over, scheduling restart.
Dec 14 18:05:48 mail systemd[1]: Stopped freeswitch.
Dec 14 18:05:48 mail systemd[1]: Starting freeswitch...
Dec 14 18:05:50 mail systemd[1]: freeswitch.service: PID file /run/freeswitch/freeswitch.pid not readable (yet?) after start: No such file or directory
After much research and trial and error, I finally found the solution. I had to change the PIDFile statement of the freeswitch.service file.
