This won't remove cpuacct from the mounted hierachy:
# mount -t cgroup -o cpu,cpuacct xxx /mnt
# mount -o remount,cpu /mnt
Because for this usage mount(8) will append the new options to the original
options.
And this will get you right:
# mount [-t cgroup] -o remount,cpu xxx /mnt
Also document how to specify or change release_agent.
