Patch in newer kernel during install?


FC3 has a bug (bugtraq 138590) that keeps my megaraid driver from getting built, so I need to be able to patch in a rawhide FC4 test kernel, which is supposed to have the problem fixed. Can I just run an install and tell it this is an additional package I want installed, after burning it to a CD? It's an rpm.

Generally, yes, you should be able to add in whatever kernel rpm you want.

There are some gotchas I can think of off the top of my head:

- have a backup of your really important data (preaching to the chior, I hope)
- make sure you install, not upgrade the new kernel and modules rpm -ivh kernel-blah.arch.rpm to make life easier to boot the old kernel, should you need
- make sure you upgrade to a compatible version of modutils
- check /etc/yum.conf to exclude those packages you install above from being automagically upgraded when you do a yum update

If you do that, you should have no problem. If there are any other dependencies that rpm asks for, (shouldn't be, but you never know,) take a long hard look to make sure you don't install something that conflicts with your other kernel.

You know, on second thought, you may run into some dpendencies that rpm won't know about if you are using LVM, md, etc. but those generally are not a big deal.

Cheers!

Thanks. I was apparently confused when I posted this: the bug existed in the ISO install kernel, thus you could never get to the additional packages part of the install, so the kernel rpm was irrelevant.

Hacked up a dd for the legacy megaraid driver and did the install with the buggy base FC3 distro.

Congrats on your RHCE. I forgot to "chkconfig iptables off" before scoring and ended up with a RHCT....
