Hi
Some time ago there was a discussion on the above subject. I have scanned the past few month's mailing list archives and cannot find the relevant mail(s).
Could somebody please repost the solution or point me at the correct resource.
I would also appreciate advice on how to do this on a RHEL4 server being updated with up2date.
Is it safe just to delete the old kernel and initrd files from the boot partition and the grub conf file?
TIA

I dunno answer to limit kernels retained.
No, simple deletion is not a good idea.
What we do is this
rpm -qa | grep kernel
Then we use yum to remove the ones we do not need
yum remove kernel-whatever-version-etc
and/or other items as necessary

What you want is:
# yum instal yum-utils
followed by:
# package-cleanup --oldkernels [--count=x]
where x defaults to "2" (i.e., keep two older kernels).

Of course you'll handle the typo and type
yum install yum-utils
(for those who are too literal for their own good : )
followed by:
# package-cleanup --oldkernels [--count=x]
where x defaults to "2" (i.e., keep two older kernels).

I recently discovered that if you have both the uniprocessor and SMP kernel packages installed, which I believe is the default behavior, then package-cleanup won't remove the SMP packages. I had to rpm -e those myself.
Maybe there's some other reason that it missed those ...

I get an error:

How to deal with that?

Unless you are really hurting for disk space on your boot partition, it is safe to leave the extra kernel images there. If the clutter on your grub menu bothers you, you can simply delete them from the grub.conf file so they don't show up. I generally keep 2-3 older kernel images around just in case newly installed ones won't boot for some reason.
Alfred gave some good advice for keeping this neat 'n tidy with the yum-utils package-cleanup command.

Hi, I use this within my kikstart scripts: if [ $(rpm -q kernel | wc -l) -gt 1 ]; then rpm -e $(rpm -q kernel | sed '$d'); fi if [ $(rpm -q kernel-smp | wc -l) -gt 1 ]; then rpm -e $(rpm -q kernel-smp | sed '$d'); fi
