So, systemd now puts every service it starts into its own cpu cgroup (in addition to the cgroup in the systemd cgroup it is already put in). In the general case this is a lot more useful than binding things to a TTY, since almost nothing that runs on a normal system actually has a TTY. Basically only "make -j" has. man-db hasn't. update-db hasn't. firefox hasn't. Nothing has. I think priority should be to add finer grained group scheduling between services and apps, and then as last step to that even between multiple ptys that a single gnome-terminal manages, but this is not where you should start. It's were the story ends. Lennart -- Lennart Poettering - Red Hat, Inc. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
