According to these docs an MTU can be specified in the kickstart script. It doesn't say much more than that though. http://www.centos.org/docs/5/html/Installation_Guide-en-US/s1-kickstart2-options.html The reason for nfs and an mtu of 4500 is complicated and not in my control. This is being used in a beowulf cluster environment. The process I'm following is currently working for kickstarting Fedora Core 4 installs, so I am hopeful it will work in centos.

Curious why your using a MTU of 4500?
