+Subject: [PATCH] systemd: clevis-luks-askpass: exit cleanly with SIGTERM
+
+Especially when running in early boot, clevis-luks-askpass may be
+looping because e.g. we still have devices remaining to unlock, as
+per crypttab, or we were unable to determine if there are any devices
+left to be unlocked.
+
+Eventually we may receive a SIGTERM, from e.g. systemd and we should
+exit cleanly in this situation.

   since that changed in v14. Check and update it, if required.
