+Subject: [PATCH 2/2] pixz: don't add trailing index to tarballs
+
+If pixz detects the input file is a tarball, it adds a trailing file index to help in seeking the file.
+However, this trailing index is causes decompression errors with xz -d and systemd-importd.
+
+For compatibility with these tools, force pixz to never add this tarball index.
