Comment 8 for bug 332945

@C. Cooke: that would need to be (at least) 24h for security updates, as many people delay installing fixes until the beginning or end of a day, to minimize the interruptions...

@Matthew Paul Thomas: one problem with the "popup update-manager" method is that it is not persistent. If I close that window (which I do because I don't want to install them now and it pollutes the "window list"), there is no (permanent) reminder for the updates anymore.
