No, you write this configuration file, though now it is possible to dump the current configuration using cgsnapshot. > For library to interface with cgroup VFS, is there a need to run crulesengd > or any other deamon ? No. > To use library, what are the steps needed ? Use the API, and build linking against the library and run the application. As long as you have the necessary permissions for the filesystem group, it will work. > If I modify conf file (which has groups/subsystems defined) via editor > instead of VFS cgroup files, then how does kernel get this update ? It doesn't. You will need to reload the configuration. > If a task is in multiple groups and in conflicting and overlapping rules, > then which one(s) get applied ?
