My Scottish co-author and dear friend referred to such cases as "giving users razor blades, and telling them to go play on the freeway." After 1/2 dozen fedup upgrades during testing, on average the downtime portion of the upgrade was between 25 and 40 minutes. On a five year old laptop, with 4GB of RAM, and WDC Scorpio Blue rust drive (the new computer with SSD did the fedup upgrade in less than 10 minutes). Meanwhile, a yum upgrade involves a transition from download to upgrade without notification, concomitant with the potential for arbitrary and untimely implosion that could hose the entire upgrade. And this is on a supposedly important computer that can't be down for 2 hours? Umm? I really don't understand this thread.
