(It > might be hard since it is full disk encryption, including the OS). To unmount your root fs, you'd essentially need to shutdown. To do that, you'll have to tweak gconf2. Note, I haven't tried this myself, but it looks like it should work ;-) Use either gconftool-2 or the gui editor to change the value of the key /apps/gnome-power-manager/actions/sleep_type_ac from 'suspend' to 'shutdown'. There are some other keys in that directory (e.g. 'low_ups') whose default values are 'hibernate' that you'll want to change to 'shutdown' too. HTH, Matt
