I must vociferously dissent.
You like having one big file you can edit to configure the system. I don't.
I see it as one big fragile way to guarantee the system is as easy to keep
from bringing up as possible. There *MUST* be a way to make the system as
robust as possible *EVEN IN THE FACE OF MISCONFIGURATION*. If you screw up a
monolithic rc, or a monolithic rc.conf, you're *FSCKED*. If you mess up a
script that's part of a series of scripts that bring up the system, you're
much more likely to be able to bring it up anyway and fix the problem, and
even to restore the broken service without a further outage.
Put simply, do we want the system to join the 90s? Or do we want to keep
looing like v7? People are using BSD to provide real production services to
real people, and in that kind of environment, hardening the system against
admin screwups is a Seriously Good Thing.

Fine. Just don't make it the standard config. The split rc.d is a step - or
sefveral steps - forward.

You may consider this a strong vote for making and keeping the system as
maintainable and robust as possible, and rc.d is the Right Way to get there.

People maintain systems every day without resorting to that kid of
interface...in the Real World. You know, where admins are overworked and
underpaid, and screw up from time to time.

How much more reliable and stable and robust can we make the system?
