Is this what you're looking for? https://www.kernel.org/doc/Documentation/power/freezing-of-tasks.txt User space is usually controlled by ("legacy") pm-utils, which simply executes a bunch of scripts (packaged and user provided) in various stages. It works reasonably well but is of course fragile - typical scripted duct tape. systemd has its own (IMHO much less fragile) way of doing things: http://www.freedesktop.org/software/systemd/man/systemd-sleep.conf.html Hope this helps. -h -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
