@ -134,9 +134,6 @@ Features:
sufficient to build a link by prefixing "http://" and suffixing the
CODE_FILE.
* when outputting log data with journalctl and the log data includes references
to configuration files (CONFIG_FILE=), create a clickable link for it.
* Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can
make clickable links from log messages carrying a MESSAGE_ID, that lead to
some explanatory text online.
