Package: prosody Version: 0.10.1-1~bpo9+2 Severity: important ** I'm reporting this from a different box than where it occurrs. **
My xmpp box runs stretch. After I added stretch-backports, which upgraded prosody to 0.10.1-1~bpo9+2, it would not run. The systemd file tried to use /var/run/prosody/prosody.pid for the pid. That matched what the cfg file specified. But the directory /var/run/prosody does not exist. The systemd file has: RuntimeDirectory=prosody but that did not create a usable directory. I had to switch both files to put the pid elsewhere (in a permanent directory to which the prosody uid has write permission) in order to get prosody to start. This did not occur with stretch's 0.9.12-2.
