And if you get into a situation where the machine reboots whether you
desire it or not?  Power, cosmic ray hit, dead cooling fan, other?  It
happens.  Even with UPS mains and redundant power supplies.  Hardware
doesn't last forever.  Will it boot?  If so then great.  If not then
you have a nasty problem to sort out and the machine is down until you
do.  I would rather know about it on my schedule rather than its
schedule.

Whenever I come across a machine that has been running continuously
for a very long time one of my big worries is that someone has
installed something perhaps hackishly and that the boot for it is not
correct.  This could mean that the machine won't boot.  Or it could
mean that the daemon won't be started.  Or other variations.

Therefore one thing that I always try to do before *I* work on a
machine like that is to reboot it first.  Then if there is a problem I
know it is a pre-existing problem and not one that I created by the
new work upon it.  And I schedule it for a time convenient to me when
it isn't going to be a panic.

If you have a machine that will not come up from a clean boot then I
think that is a scary situation to be in.
