Pottering's code appears to just be a proof of concept. It really doesn't make sense to have this behavior in a bash initialization file. Not to mention you'd have to launch your X session from that bash instance (and you'd have to be using a bash-compatible shell to begin with or port the code your preferred shell) to get the desired effect. That is nice, but I'd rather see how this would be properly implemented in userspace. Pottering was eager to prove the performance increase could be applied to userspace, not how he would integrate this approach with current Linux desktops. Also, as Linus noted, it would be nice for users to just perform a standard system update and all of the sudden have a more responsive desktop on reboot. If it can be done in userspace, distros should flesh out the userspace code and disable the kernel feature. Once it is reasonably handled in userspace across Linux distributions it can be removed from the kernel.
