How to reload after changing a file in /etc/sysctl.d/?
According to /etc/sysctl.d/README.sysctl
After making any changes, please run "service procps force-reload" (or, from a Debian package maintainer script "deb-systemd-invoke restart procps.service").
Is the service command still "state of the art"?
man service
service - run a System V init script
Now I am unsure. System-V init script ... Wasn't that replaced by systemd long ago?
I use Ubuntu 22.04.
