We have CentOS 6 manual installation working by PXE booting from a RHEL5.6 PXE/TFTP server. However, when we add a Kickstart file in the PXE configuration:
kernel CentOS-6-i386/vmlinuz append load_ramdisk=1 initrd=CentOS-6-i386/initrd.img network ks=nfs:130.226.86.4:/u/rpm/kickstart/ks-centos-6-clean-i386.cfg
then the CentOS 6 client install reports "Unable to download the kickstart file". The console 3 reports "failed to mount nfs source". We believe the NFS server is OK because we can install CentOS5 clients in this way.
Perhaps this problem is related to this RHEL6 bug? https://bugzilla.redhat.com/show_bug.cgi?id=653655
However, on the centos list I see some people who apparently go Kickstart to work with CentOS 6 - but how did they do it?
Question: What special configuration is required for either 1) PXE or 2) the DHCP server?
Thanks, Ole
