Computer systems can also fail due to being stressed in operation, as anyone who has lost a system due to a disk filling up with log information knows. The big difference is that since `manufacture' is cheap and reliable, we generally don't use the software part of a system for long -- we make a new one each time we start to use it. I even start a new emacs now and again :-). For an operating system in particular MTBF is very meaningful. -- rjc@cstr.ed.ac.uk Ex-keeper of the speech daemon, which had a MTBF of minutes.
