+Subject: [PATCH] Use -set-cookie when running erl in ejabberdctl.template.
+
+This patch converts the ejabberdctl.template to use erl's
+-set-cookie option when an .erlang.cookie file is found in
+$SPOOL_DIR. This will help for installations where ejabberd might
+be started by one user, but ejabberdctl might be used by a
+different user to manage it. For example, in Fedora ejabberd is
+launched by systemd as the ejabberd user, but users might want to
+use "sudo ejabberdctl" to manage the node.
