+Subject: [PATCH] Treat absolute paths as relative paths during extraction
+
+Tell libarchive to use the path for extraction that Ark uses internally.
+In addition, set the ARCHIVE_EXTRACT_SECURE_NOABSOLUTEPATHS flag to avoid
+that absolute paths are used by accident.
+
+(cherry picked from commit cc9ea9e89c1c679d398809e94f1217b1f73c4b48)
