Package: systemd
Version: 228-2
Severity: wishlist
Tags: patch
Dear Maintainer,
systemd currently logs many informational messages to the system log and
does not exclude any of these messages from logcheck, which results in
an overwhelming number of systemd log messages being reported.
The logcheck maintainers recommend that packages maintain their own
logcheck rules.[1] To that end I'm filing this bug report along with
the rules that I am currently using. They are based on the rules from
the Debian Wiki[2] with additional rules and additional work to organize
and structure the rules based on the log statements in the source code.
Although the rules on the wiki attempt to match target/service/unit
names, I think this is futile, especially given the low-security nature
of such messages, and instead exclude all start/stop/restart messages.
This has 2 known false-negatives noted in the rules, which are difficult
to exclude due to the lack of negative lookahead in the POSIX regex
language (although it could be done if desired).
To use the file, install it as /etc/logcheck/ignore.d.server/systemd
Thanks for considering,
Kevin
