How the Centos 5.0's kickstart initrd.img is build??
by Guolin Cheng 31 May '07

31 May '07

Hi, Any one know how the Centos 5 kickstart initrd.img was built? I'll be very appreciated if any light can be shed on this topic. The basic problem to be solved here is: how to build a custom vmlinuz+initrd.img for Centos 5 kickstart with my own custom built kernel? I am not sure mkinitrd is the right tool for this purpose? If do, which are the modules I should include with '-preload' options? And if there are any extra files/steps I should include/follow for the initrd.img file? Not sure how the stage2.img is loaded by kernel after initrd.img is loaded and run. Please help. --Guolin

cobbler or puppet in Centos5

while i'm on a Centos5 kick, I was just curious if I simply needed to add a repo or if building these was a matter of waiting in terms of Centos5. Am trying hard to stay away from Fedora if possible... -krb

RE: custom kernel for Centos 5 kickstart?
by Guolin Cheng 30 May '07

30 May '07

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? --Guolin -----Original Message----- From: kickstart-list-bounces(a)redhat.com [mailto:kickstart-list-bounces@redhat.com] On Behalf Of Byrne, Nicholas Sent: Wednesday, May 30, 2007 3:40 PM To: Discussion list about Kickstart; centos(a)centos.org Subject: RE: custom kernel for Centos 5 kickstart? 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/ ________________________________ From: kickstart-list-bounces(a)redhat.com on behalf of Callahan, Tom Sent: Wed 30/05/2007 18:58 To: Discussion list about Kickstart; centos(a)centos.org Subject: Re: custom kernel for Centos 5 kickstart? 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.

GFS on 4.4 vs. C5
by Karl R. Balsmeier 30 May '07

30 May '07

I am doing research on getting an operational GFS setup on 3 servers I have centos 4.4/64 built on. I can of course upgrade the to 4.5, but is it smarter to try centos 5 for this or can I get away with getting this working on 4.4/4.5? (basically trying to eliminate the need to visit the colo.) -krb

vmware tools in CentOS5 guest?
by Les Mikesell 30 May '07

30 May '07

Does anyone have vmware-tools from the recent server 1.03 release running in a CentOS5 guest VM? vmware-config-tools.pl goes through the motions except for building the vmhgfs module (which it says is only needed for mapping the host file system) but then X won't start up with the new configuration. -- Les Mikesell lesmikesell(a)gmail.com
