+Dear $USER$,
+
+the automation to check activity in the systemd dist-git repo [1]
+determined that you haven't done any commits in the last two years.
+
+To decrease the potential for unauthorized access, such checks will be
+executed periodically. Not-used accounts with write access to the repo
+will be downgraded to "ticket" (no write privileges).
+
+If you want to retain access, please reply to this mail.
+Otherwise, in two weeks, your access mode will be changed to "ticket".
+Even without write access, anyone can open a pull request in pagure,
+so write access is not necessary to contribute to the package.
+Obviously such changes not permanent, so even if your access mode is
+downgraded, it can easily be restored later on.
+
+Yours friendly,
+./owner-check.sh
