Hi Jimmy,

That hasn't been my experience but your mileage may vary.

Sometimes mine do. Who are you to say otherwise?

For the record, one of my desktops has been up for 262 days. One of my
*windows* desktops has been running for 35 days. Maybe I'm just better
at keeping my equipment online. ;-)

And all of this is *why* we picked 12 months instead of 3 or 6 back
when the policy was written. So that there would be *plenty* of time
for a successful renumbering, despite the very significant
difficulties and pain.
