F9: Network address problems

    I have had issues with Fedora lately (past 4 version now) that most 
of the time I have gotten past after a while, but don't have anything 
uniform to solve this. Here is the situation:

When installing a new system to replace an old one, I set up the new 
system with it's own unique IP address (say while keeping 
the old server online to serve traffic (say After getting 
the new system up and online, tested Q/C'ed and ready to deploy, I take 
it off the network and re-IP it. No big deal. What I do to do this is:

ifconfig eth0 netmask

vim /etc/sysconfig/network-scripts/ifcfg-eth0
and make changes as appropriate. After that I adjust all the programs to 
use the new address and test them with it as well. It works perfectly... 
until a reboot...

Usually what happens is Fedora will boot happily, for the most part, but 
network socket Dependant  items, like ssh, httpd, mysql, radius, ldap, 
etc fail  when coming online since there is no IP address assigned that 
matches what they were configured for (the new/changed IP). When I 
re-run the network script in init.d (or service network restart, same 
thing) everything network wise comes up fine, no problem. It is just on 
boot that it fails.

Does anyone have any ideas on what I could have missed, and/or what I 
could improve with this?
