Ok.

Would it make you more happy if i rephrased to something like «From time to
time there are serious bugs in the kernel which requires immediate upgrades,
or we might experience kernel oopses that might keep the system running, but
will disable certain hardware, such as raid controllers...»

The point is that thare _are_ situations where a reboot is the only solution,
and there are situations where a reboot might be the simplest and quickest
solution - even with Linux.
And in these situations, we do experience from time to time that the system
will not shut down properly, but hang around in the shutdown process "forever"
(or until someone comes hands on to press "reset").
Yes, I know there are hardware available that will make it possible to
powerswitch the systems remotely, but this might not allways be a feasible
solution.

That is why I hope the discussion about shutdown time also will lead to a
shutdown process that is really shutting down - or rebooting - the system,
every time, in every situation - no matter what some process might be waiting
for.
