It is really "a long time ago" that I installed something over PXE but I think these images are just normal desktop images and use the normal desktop kernels. But I may be wrong. If I'm right you can contribute by generating different PXE netboot images. Or you can do a feature request in launchpad. > > Please let me know if i need to furnish additional information about my > setup. > > Please suggest/guide further. > There are many options available to do things a little different! But I think this is something every SysAdmin must master for himself/herself. Just something for you to look further: FAI (search for this on the Internet) and http://en.wikipedia.org/wiki/Comparison_of_open_source_configuration_management_software. These may or may not help you. It depends on your network, your skills and your willingness to learn. If I where in your situation I would write a small script that installs the server kernel, remotely deploy this script on every server, reboot automatically every server and after a restart deinstalls the desktop kernel. Then I would take a closer look at the content of your PXE install image.

I do use ks.cfg file. Basically network based installations. I have tftpd/dhcpd/apache2 servers to serve this purpose The issue is that after installing ubuntu 8.04 server on the client host, I see the generic kernel being installed and not the server kernel. I did manually by running apt-get install linux-image-server on the client host. It installed the server kernel which is a manual method. is there a way to fix it on the pxe image itself so that whenever new clients are being build with Ubuntu 8.04 server.

Re: Ubuntu Server: Kernel Configuration Considerations
you are using a preseed.cfg file right? You want to have this in there: # The kernel image (meta) package to be installed; "none" can be used if no # kernel is to be installed. #d-i base-installer/kernel/image linux-generic d-i base-installer/kernel/override-image string linux-server That is what picks which kernel is should be running I believe. I have documented allot of the PXE boot stuff here: https://www.digisoftinc.org/wiki/index.php/Ubuntu_preseed.cfg_installs_off_PXE_Boot As far as fixing it on each machine that is beyond my expertise but I believe you would have to get the ubuntu server kernel...compile it and then add it to your grub list. Sorry if you are looking for a direct fix for each server.

Re: Ubuntu Server: Kernel Configuration Considerations
I think you want: d-i base-installer/kernel/override-image string linux-server what do you have in your file for that?

Ubuntu Server: Kernel Configuration Considerations
Hi, The issue is that we have built ubuntu using kickstart/tftp/pxe image on all the 300 servers. The issue is with the pxe server. We found out that the running Kernel on all the ubuntu hosts are 2.6.24-16-generic and not 2.6.24-16-server. Please suggest me whats the best way to set it to correctly to 2.6.24-16-server on all the hosts running ubuntu 8.04 server(Hardy) Thanks and Regards Kaushal -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
