Hello All,
I'm trying to get kickstart to work through pxe. So far I've set up dhcp server, tftp and so on. But it seems at some point I always get stuck because the iso file is write-protected.
I've tried remounting it rw, and I 've dd the iso first, I then get EM not a block device.
Any help would be appreciated.
Greetings, J.

I'd always tend to just expose the install image via HTTP.

Hello John,
thanks for the reply. I found a useful tutorial on kickstart/http here: http://www.tomsitpro.com/articles/kickstart-linux-automation,2-798.html but if I understand it right, via http is not an unattended install. You have to have a boot medium.
If I'm correct people do unattended installs all the time, so I don't understand why all the tutorials I try fail on the same point. I must be doing something wrong.
What I did on my last try was:
Download Centos dvd to /tmp mount -o loop /path/to/centos-dvd.iso /mnt rsync -azvp /mnt/* /var/ftp/pub/
But subsequently I can't change anything in /var/ftp/pub because of read-only file system.

Basically in order to boot from the network you need the contents of os/$arch/images/pxeboot/ for your system architecture. You can then use kickstart to point to a media you want to use for the actual installation. This can be that of cdrom, url, nfs, etc. You pass the kickstart parameter to your client using the 'ks=' parameter. the installation media can be from a local rsync of the CentOS repository (to save money) or to a mirror of your choice that may be local to you. Feel free to ask any questions.
