Public bug reported: On a desktop system, on AC power, pm-utils reset the vm.dirty_ratio and vm.dirty_background_ratio at boot time.
When setting these variables using sysctl.conf, they are silently reset by the /usr/lib/pm-utils/power.d/laptop-mode script shipped with pm- utils. The only way to give specific values to these variables using sysctl is to remove this script.
