And...that is where binary logging should stay, until it can be eliminated entirely.
I don't even know why I'd care if systemd uses a binary representation internally, as long as it can give me human-readable logs with only text tools.
Only showing binary logs with systemd tools is a misfeature of the type "exposing the implementation". Userland requires a UI, and it's bad UI, and frankly bad Unix.
Now then, I hear you can somehow configure systemd to echo a copy of its logs to rsyslog. But, and maybe I'm just a fool with poor GoogleFu, but I tried for a couple hours to get this working and only found company for misery on the mailing lists.
If any systemd fans can point us to a quick-n-easy HOWTO on getting text [r]syslog working under systemd, then by all means shut a few of us up. Tell us how there's plenty of documentation too, we'll all hang our heads and wander away.
