AIX sort of gets a pass here on account of being on the weird side
to begin with and bonus points for not using DB/2 for primary log
storage ;-)

Except you now have to do the additional step of extracting the
data from the binary logs and _then_ apply the regex filter you
were going to use in the first place, which makes the logs less
accessible. All of my systemd running machines still get rsyslog
plugged into it so it can deliver the logs to my central log host
(which then dumps them into PostgreSQL) - and to enable a quick
rummage in the local logs via less & grep.

Kind regards,
