Well, yeah, that's not what I meant.
My point was the early boot messages which accumulate and get dumped to
the syslog socket in a short period of time (with possibly no reader up

If you need that kind of throughput, using the imjournal module might
possibly be the better choice (would need some testing, how mature
imjournal is). Unfortunately, it's not really possible to ship a default
rsyslog configuration, which uses imjournal and works both under systemd
and alternative inits.

Why is it that all of the instruments seeking intelligent life in the
universe are pointed away from Earth?
