which systemd systemctl services to disable or mask?

Post by ron7000 » 2019/06/03 15:46:16

Installing server with gui, everything seems to be running fine on server however the /var/log/messages has many entries such as Started Fingerprint Authentication Daemon and that is repeated many times. I want to clean things up.

Code: Select all

systemctl list-unit-files
{not typing all in}
369 unit files listed.
Among the many in /var/log/messages there are these kind of entries: dbus-org.freedesktop.***.**
I don't want to see this, among others.

Is there any good list showing what services either should be, or can safely be, disabled or masked?
My understanding is a service setting of static basically means it is enabled (if needed) and would be started [dynamically?] be some other service it is a dependency to?

As hunter86_bg suggests - resist the urge! You may not want the services today, but it won't be long before you decide you want to install something that expects them to be running.

If you want to filter some of the messages , you can do the following:

Code: Select all

echo 'if $programname == "systemd" and ($msg contains "Starting Session" or $msg contains "Started Session" or $msg contains "Created slice" or $msg contains "Starting user-" or $msg contains "Starting User Slice of" or $msg contains "Removed session" or $msg contains "Removed slice User Slice of" or $msg contains "Stopping User Slice of") then stop' >/etc/rsyslog.d/ignore-systemd-session-slice.conf
systemctl restart rsyslog
You might have to replace '$programname == "systemd"' with '$programname == "systemd-logind"'.
