No, it would be used for automating backups, or implementing suspend->hibernation transitions. For example, right before the machine suspends, I would schedule it to wake up in a hour. If I get woken up by the rtc alarm (and not by the user through a lid open), I might: - check that I'm plugged into the AC, it's night, and in the vicinity of the server that handles my backups and so backup the system. - check whether the battery is low, and hibernate the machine (if it supports it, obviously). We cannot do that if we can't make out whether the wake-up came from a user action, or the alarm we set.
