Hello,
Since some times I see a lot of lines in journalctl about rtkit-daemon. Seems only information and not warnings.
I observed that starting firefox and opening new tabs generate each time two or three lines in journalctl.

.
AFAIK rtkit-daemon is a service that changes the scheduling policy of threads on demand.
There is no man about rtkit or rtkit-daemon only rtkitctl but without information about the messages or debug level.
A file /usr/lib/sysusers.d/rtkit.conf is also present but I did not find any information therein
# cat /usr/lib/sysusers.d/rtkit.conf
#Type Name ID GECOS Home directory Shell
u rtkit - 'RealtimeKit' /var/lib/empty -
The service definition for rtkit (/usr/lib/systemd/system/rtkit-daemon.service) doesn’t seem to contains a message parameter.
Starting the command
/usr/libexec/rtkit-daemon --help
gives some available parameters but I don’t see therein anything about messages.
Is there a parameter or a setting that would eliminate these superfluous messages?
Many thanks in advance
Philippe
