When using Docker there may be a large amount of messages logged in the system logs like this:
│Aug 17 20:46:16 desktop systemd[1]: run-docker-runtime\x2drunc-moby-d886bd7e729e55be366862c87dfcf9c8480196194279f9ff01dca27401d1bac7-runc.cdhFsU.mount: Deactivated successfully. │
To ignore the messages, create a configuration file for the systemd run-docker mount which sets the log level to notice.
sudo mkdir /etc/systemd/system/run-docker-.mount.d
cat << EOF | sudo tee /etc/systemd/system/run-docker-.mount.d/10-silence.conf > /dev/null
