Comment 18 for bug 244838

Concerning the related blueprint: "Integration of the laptop-mode-tools package with the rest of the default system".

 * It looks less like integration and more like droping plus reimplementation and repeating errors. laptop-mode-tools is a very well maintained package widely used on debian laptops. Mangling the three tasks of power management (https://wiki.ubuntu.com/PowerManagement) into one (acpi-support) already failed miserably once. Use small tools specialized for its task. Why not adeqately calling the laptop-mode-tools script from pm-utils so that they do not trip over each other. (possibly deactivating/changing and properly commenting some of the laptop-mode-tools options) But dropping laptop-mode-tools from the distribution really does not look like a solution at all, much more if crucial laptop_mode (disk idleing) gets no support.

 * Deliberately buffering disk writes with laptop-mode-tools of course means loosing data on crashes (but not on battery run out). A reason not to touch (disk idleing / laptop_mode) with pm-tools but make laptop-mode-tools work in a pm-tools environment.

 * ext4 is supported by laptop-mode-tools since 1.47-1.
