CentOS - Mar 2012 - Kickstart network issues

Hello all -

(Please forgive me if I sent this msg twice, first one didn't seem to go
through)

I searched through the archives and did not see anything about this (along with
google), but if I missed something please don't hesitate to send me some
links.

Basically I have hit a problem that I cannot figure out at this point and seemed
to have ran out of ideas via Google or the documentation.

I am kickstarting (using cobbler) CentOS 6.2 installs over a private network
(can reach the Internet). Part of the installations is to go grab various
configuration files, rpm's, etc that are located both internal to the
network (different subnet) and externally on the Internet somewhere. This
problem seems to be intermittent since it works half of the time, but not the
other half.

Any of my kickstart scripts I have that use local commands (not wget'ing
files) work just fine no problems. However when it comes to getting things from
the network, it does not always get those files. Usually this errors out with a
cannot resolve hostname error or no route to host. I have tried the following to
overcome this:


1)      During post-install, add a network start and sleep for 120 seconds to
give it time to come up.

2)      Made sure that the "network" commands in the kickstart
included -activate

3)      Tried making the downloads not depend on DNS which still does not work
(no route to host).

Are there any tricks to ensuring the network comes up during post-install for
kickstart?

By the way, after the kickstart is done and the VM boots up, there are no
changes that need to be made to get the network up and running like normal...
DNS, etc work fine immediately.

Thanks for any help,

Daniel

For your RPMs, I'd definitely suggest setting up your own local repos 
within Cobbler and serving up that way on install - each repo doesnt have 
to be used for each system you configure...or it can be...

For your files - you might consider using Puppet and have it deploy them 
post install from a Puppet master?

I know this isn't exactly what you are asking about - just though I'd 
mention it in case its worth while - as I sort of do something similar 
myself but using Cobbler/Puppet....
