Hi all, I'm currently trying to make my RHEL 5 kickstart environment working for RHEL 6. So far everything looks OK - but when I use the special kickstart file, that takes some arguments from the user it fails. The problem is that I have to change the tty (chvt) to get the interactive stuff working - but for some reason doesn't it have the same behavior as we had in RHEL 5. It still changes the tty but after that, the script doesn't process further. I personally think that it has something to-do with the tty change (but I also can be wrong). So if somebody has a working example, I would be really grateful as I've tried almost everything without luck. My kickstart file is build as follow: # Test Kickstart # Installation specification install # url --url http://url_to_repo cdrom text key --skip lang en_US.UTF-8 keyboard sg-latin1 %include /tmp/network-include rootpw --iscrypted xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx firewall --disabled authconfig --enableshadow --enablemd5 selinux --disabled timezone --utc Europe/Zurich firstboot --disabled logging --level=debug #
