[LAU] cgroups in kernel, no libcgroup... RT?

[Renato]

Hello, CONFIG_RT_GROUP_SCHED is enabled in the default archlinux
kernel. Reading this page

http://trac.jackaudio.org/wiki/Cgroups

I'm not sure I understand the second paragraph, "Why does it touch
jackd". If I do *not* have libcgroups installed (which is the default
on arch, the package is found only in the AUR user's repository, not in
official repos), am I still ok for doing RT?  

cheers
