That was just an example of what I'm doing.  In reality logtail's in
there, but it made the example line too long.

Yes, i use logcheck religiously, despite the absolute lack of logcheck
rules maintenance that exists in most packages not installed on a
default system (looking at you nginx, postfix, bind9, cron, clamav*,
openvpn, dovecot, opendmarc, monit, and openntpd).   I'd submit the
improvements to the appropriate maintainers, but I dislike rejection.
