Yet, it works pretty well most of the time. I've done it at decent scale on
production machines with no real issues -- and, most critically, with
*fewer* issues than on unpatched systems.

Real issues do _occasionally_ occur, but so do bad disks, failed ram, bad
offline updates, etc., etc. Fear over lack of atomicity is letting "it's not
perfect!" get in the way of real world usefulness.

Additionally, these updates aren't _silent_ -- they're logged and there's an
e-mailed report.
