+Subject: [PATCH] Fix rpm 4.15+ compatibility
+
+Before rpm 4.15, rpm's python3 bindings would return string data as
+bytes.  This script worked around that behavior by proactively decoding
+them, which was a noop on python2, retaining compatibility.  In rpm 4.15
+this behavior was corrected so that string data is returned as utf8
+strings, which had a side effect of breaking our workaround on python3.
+The change was also backported to RHEL as rpm-4.14.2-25.el8, available
+since RHEL 8.1.  The last Fedora release with the old behavior was
+Fedora 30, meaning all OS's with the bytes behavior are EOL.  We can
+just use the strings as is, which works on all current Fedora and RHEL
+releases.
