I've never attempted to lecture anyone, just show a point. I apologize
if it ruffles your feathers.

This is completely out of context. I only mentioned nuclear plants and
telcos to show why supervising a service is important. This wasn't a
discussion about what NORAD, military, or you personally did to run
such systems. I don't have any personal experience with those systems,
but I do want to supervise software under Unix, and just wanted to show
why. You could easily replace 'Nuclear Reactor' with 'Website' in my
former message, and the point is the same, really. A website, for some
people is mission critical too. The point about Erlang is
it's nice to see a language that attempts to give a programmer fault
tolerance, and from all I know that particular switch is a very
successful product, but that's beyond the point.. If a Unix tool can
do something simple, like restart a service when it goes down, why not?

No need for the 'I've been there done, that, you are an idiot' type of
