Hi, I'm in the process of simplifying my structured logging config. Most of my systems now have journald shipping local logs to syslog-ng via the `system()` auto-expanding source. While this is convenient, as it makes it possible to use the same config for all my systems (systemd and rest of world), it also makes it impossible to configure the underlying driver's defaults. The task at hand is shipping the journald additional fields, which would be easy to do using the following excerpt from the documentation: source s_journald { systemd-journal(prefix(".SDATA.journald.")); }; This is not possible of course using `system()`. I've got a couple of ideas on how to handle this, but I'd like to hear other (probably less insane than my own) ways first :-) Cheers
