So here is what I did: - open a regular (non chroot) session. - cd to /media/-/ - mount /dev/sda1 boot /dev/sda1 is the /media/-boot/ drive. I found this out by doing a df and looking at the mappings. - the mount has to be done in the NON chroot session because the chroot session doesn't have access to /media and its /dev doesn't have the boot directory in it. What all this does is mount the boot partition to /boot for the chroot session, just like the linux OS does when it boots for real. Once that is all done, do this: - open a chroot session - cd to /home/xxx/Download, where the rpm files were that I installed - rpm -i kernel*rpm. This gave me an obscure error - rpm -F kernel*rpm. This worked - rpm -q kernel - this listed the f12 kernel. - rpm -e kernel...rpm for the f12 kernel. This worked. - when I checked /media/-boot/ in the non chroot session, the f12 files were gone. I will now reboot to see if my machine runs. One thing I learned in all this is that its really, really nice doing a rescue from a Live CD because you have full access to the Internet and you can open both chroot and non chroot terminals to the hard drive file system and operate as you need to. The chroot sessions allow you to use all the tools (in the correct versions) that you have installed on the hard drive. The non chroot sessions allow you to access the hard drives from a more global view, ie via /media/-/, etc. Pretty neat. I am going to reboot now...
