+  o Distribution:
+    - Explicitly disable RunAsDaemon in the systemd unit file.
+      Our current systemd unit uses "Type = simple", so systemd does
+      not expect tor to fork. If the user has "RunAsDaemon 1" in their
+      torrc, then things won't work as expected. This is e.g. the case
+      on Debian (and derivatives), since there we pass
+      "--defaults-torrc /usr/share/tor/tor-service-defaults-torrc"
+      (that contains "RunAsDaemon 1") by default.
+      Patch by intrigeri; resolves ticket 12731.
