Hi,
Thanks a lot for your great suggestions.
I've tried ksdevice options as well. It does work for some cases. But the main problems. We have tens different network/harddrive combinations. And so it turns a simple issue into a unmanageable complex. Originally we use a custom booting kernel plus in-house sysimager solution to handle it, custom kernel fix the detection sequence problem and sysimager dumps a few tarball/images to hard drives.
If we can find a way to use a custom kernel to replace default Kickstart kernel+initrd.img. Then we can fix the problem very elegantly.
Any ideas on hacking Kickstart initrd.img?

possibly "ksdevice=" which has a number of options that are useful but it depends on what exactly he's trying to achieve. The other method i thought of is to not setup network in main kickstart but instead do it with netconfig in %post where you can use the --hwaddr switch (and determine the target interface by it's mac address).
Or perhaps, since anaconda does a good job of setting up interfaces for you, so just configure them up as you would like ignoring the fact that they may be pointing to the wrong NIC and then change /etc/modprobe.conf and /etc/sysconfig/network-interfaces/ifcfg-ethX files in %post to suite your needs (again determine the target via mac address)
The first 3 bytes of the mac addresses are the manufacture code so you should be able to work our a list for your hardware using http://coffer.com/mac_find/

I remember there being an option to define which MAC addr is defined as eth0, etc. This was something you could define on the kickstart command line.... Check out the documentation for anaconda.

Hi, Has any one tried to merge a custom kernel into vmlinuz/initrd.img for Centos 5 kickstart? Or similar Linux distribution? I am rebuilding a custom kernel from stock kernel source to build some hardware modules into static form, so that the hardware detection sequence can be altered in a hard way. Quick examples are: tg3 drivers will be loaded before e1000, 3w-9xxx be loaded before 3w-9xxx, etc. Please advice. If the object could be achieved through adjustment to /etc/modules.conf or similar files, then it could be even more fantastic. ________________________________
