I run hundreds of domains, differentially requiring a seperate
IP or not, and on clusters of networked machines, pre-staged
to cover for one or the other if one goes offline --
background services like DNS and Radius, and internal
log/management reduction.

No question but to leave the scripts alone, and edit the
config files -- even if the edit is ALSO with scripted tools
-- for one customer, my DNS maintenance driver config file
particularly runs thousands of lines (over 7000 the last time
I looked) -- and so in turn IT is also script maintained
(splits to the proper sub-host, and between the Linux farm and
the one remaining NT for people who insist it has to be on NT
<grin>) -- and main and backup MX servers

The only major hack beyond rc.local where I do this is for a
customer there I run a differential DNS (different results to
different parts of the WAN, depending on where the workstation
is, and how it reaches certain hosts) where this was necessary
-- but it was due to a need to support a grossly misconfigured
legacy Novell BorderMangler/Frame situation.

Custom routing is usually able to handled in
/etc/sysconfig/static_routes -/- I have that supporting a
network design by EDS on their private frame network (which
uses public IP's rather than RFC 1918's) -- and maintained by
people who cannot differentiate IP routing from a duck.

... I spent some time with the RH beta team effort in advance
of RH 7.1, getting option proxies in place in /etc/sysconfig/
I'd be interested in receiving offlist  a discussion of the
standard init scripts you needed to hack after RH 7.1 released
