-Stubby integration with systemd
-===============================
-
-For GNU/Linux operating systems which use systemd as a process
-manager, you might want to run stubby as a system service.
-
-This directory provides recommended systemd unit files.
-
-This setup assumes that there is a system-level user named "stubby"
-which is in group "stubby", and try to limit the privileges of the
-running daemon to that user as closely as possible.
-
-Normally, a downstream distributor will install them as:
-
-    /usr/lib/tmpfiles.d/stubby.conf
-    /lib/systemd/system/stubby.service
