Kickstart %post problem

Ray Bell — Mon, 08 Feb 2010 19:57:38 GMT

I'm install RHEL5 from a kickstart script that seems to works but aftre the %post section nothing else works. Not sure what is wrong and need some hlep: Here's a copy of the script:

You're using "%post --nochroot".

When you use the --nochroot option, your post-installation script is executed in the installer environment. For example, when you add lines to "/etc/rc.local", they won't be added to the /etc/rc.local of the freshly-installed OS - they will be added to the /etc/rc.local of the _installer environment_ which is located on a RAM-based filesystem and will go away once the system is rebooted.

If you need to use "--nochroot" option, your script must be aware that the entire new OS is located at /mnt/sysimage - i.e. use /mnt/sysimage/etc instead of /etc, and so on.

The use of tools like chkconfig will be much more complicated with the --nochroot option. Instead of

/sbin/chkconfig --levels 345 ntpd on

you must do:

chroot /mnt/sysimage /sbin/chkconfig --levels 345 ntpd on

Otherwise the chkconfig tool will modify the /etc/rc*.d directories of the installation environment, which may fail because the installation environment does not have all the things the real system has. Even if chkconfig is successful, your changes will be lost as the system is rebooted.

As far as I can see, your installation script does not actually require the --nochroot option and seems to be mostly designed to work without it.

So, I recommend that you make two changes:
1.) change the TextFile variable to:

TextFile="/root/ks-install.txt"

2.) change "%post --nochroot" to a simple "%post".
