Well, you could remove any hardware devices from the kernel, that you're sure
you don't have nor going to get within the machine's lifetime. Nics and
disk/raid controllers are good candidates.
However, this isn't really an exact science and you may not be able to cut the
time you need. So you could of course make up for it, by *delaying* the
dependant machines by 30-60 seconds. I'm sure that another 30-60 seconds on a
multi-hour outage isn't gonna make a difference.
Problem with today's modular software: they start with the modules
and never get to the software part.
