Comment 3 for bug 517732

Thanks for taking a look at this, David and Michael!
This bug report is a duplicate. The original (bug #494772) is already filed (with lots of subscribers :o).
There are some additional technical and philosophical musings that may be worth looking into. In particular, as far as I'm aware (though I'm going on a vague memory of a brief glance at update-notifier) we're checking for updates while on battery, which is almost as bad as installing them.
