Comment 1 for bug 1862265

I'm seeing and thinking the same for this.
I have only configured the following for sysconfig charm, and seeing the following juju status message "reboot required. Changes in: /etc/systemd/system.conf",
in addition to this the application status is in "blocked" status as well.

$ juju config sysconfig governor=performance

For now the workaround is to run clear-notification action.
