Ultimate goal: Create an automated installation disk for CentOS, using a kickstart config file stored on an internal website.
What I've done: Created a script that
- downloads an ISO
- unpacks it
- updates the
isolinux.cfgfile with my own menu option - recreates the ISO using
genisoimage
All of this works, and the ISO is recreated without any errors. However, when I try to use the ISO, to start an installation, the sistem always dies at:
"new value non-existent xfs filesystem is not valid as a default fs type"
Pane is dead
Unlike this question here, my error happens pre-installation, and I'm already using lang = en_US.UTF-8. I even tried en_US, but it did not make a difference.
Lines I added to the isolinux.cfg file:
label install
menu label ^Kickstart Installation
menu default
kernel vmlinuz
append initrd=initrd.img text ramdisk=100000 lang=en_US.UTF-8 keymap=us ipv6.disable=1 ip=dhcp install inst.ks=cdrom:/kickstart.cfg
I searched online for the error, and a lot of comments seem to be related to mismatching versions for init and the kernel, or corrupted files. I am not replacing any files, and the only change I make is to the configuration file isolinux.cfg. There is no mixing of files from different versions/DVDs/images.
Has anyone had/seen the above, and have any ideas on what I should try next? I've tried playing around with the options I am putting into the file, but it doesn't seem to make a difference.
