For all production server I run any reboot that is not scheduled by admins
is ultimate disaster, so it is equivalent to "bricked" machine. That
hardware can not be further used as production server, but "mere" fact or
reboot is ultimate disaster itself.
I bet I am not the only sysadmin with this point of view. That is why I
said production server is by no means comparable to sobody's home
workstation. But I bet many people have the same attitude to their home
workstations as I have to servers I am responsible for. Well, I for one
have the same attitude to all my computers, including laptops, and as a
sysadmin - to all computers of people I support.
Of course, some people may have different point of view on this, which
does not deprive me of expecting from my hardware to work without
My apologies for being edgy. These things make me such.
