+Subject: [PATCH] luks: enable debugging in clevis scripts when rd.debug is set
+ (#340)
+
+On Fedora/RHEL, the rd.debug kernel command line parameter controls
+debugging.
+By implementing the functionality inside clevis, troubleshooting will be
+greatly eased.
+See RHBZ #1980742 (https://bugzilla.redhat.com/show_bug.cgi?id=1980742).
