I used to be able to kexec into a new kernel immediately after a kickstart (anaconda) install via pxe.

I was able to do this by figuring out the current kernel version, and grabbing cmdline options by using /boot/grub/grub.conf

cmdline=$(awk /kernel.*console/'{$1=$2=""; print$0}' /boot/grub/grub.conf)

Then: kexec -l /boot/vmlinuz-$(uname -r) --initrd=/boot/initramfs-$(uname -r).img --append="${cmdline}"

Now I am unable to find what the cmdline options for the next reboot are since /proc/cmdline and the cmdline command only show me what the cmdline is for the installation disc.

How would I be able to find out what the cmdline is for next reboot now?

You can use

reboot --kexec

in your kickstart file.

This should be equivalent to your previous approach, i.e. the kickstart software then figures out the kexec parameters for the newly installed system.
