After i did a update using Redhat Network, I have more then one version of kernel. I have 2.4.18-3 , 2.4.18-3 debug, 2.4.18-4 ,2.4.18-4 debug.

After doing another update a week or more later ,new version of kernel was updated and now i got 3 kernels for me to choose when i boot up my system. 2.4.18-5, 2.4.18-5 debug.

A few qns.

i don't need 3 kernels, i will like to keep only the latest one so when i boot up the system i will only have one choice. How can i do that? Which files should i edit?

What is the diiference between 2.4.18-5 and 2.4.18-5debug?? Likewise for the above 2 version? What is the debug about? Should i choose the debug version to login ? or just the version without the word "debug" behind it?


Thanks in advance

if you use lilo, you can check your /etc/lilo.conf and edit. If you want to totally remove the older image to free up space which is located in your /boot you can refer to the /etc/lilo.conf for the older image.

I'm using grub.

You said remove issit just edit the text below?
How about the different between the version with and without the word debug?

You just need to edit out the entried for the kernels you dont need. No need to run grub afterwards. With lilo there is.
To be safe I would make a copy of grub.conf just for safety.
2.4.18 is the latest stable kernel.

Okie thanks.

What is the 2.4.18-4 and 2.4.18-4debug about?

Which one should i boot up from? 2.4.18-4 or 2.4.18-4debug?

So can anyone ans my QNS?

dude, erase all except the 2.4.18-5 if it's working fine. Delete the Debug one, you don't need it, and just boot the 2.4.18-5, that's all your need to do.

thanks dude.

But what is the different between the 2?

Hi,
As far as I know, for normal use you need not boot debug kernel. It's for developers with builtin debug symbols.

By rpm -qip on this package you will see...

This package includes a kernel that has the IKD kernel patch built in
and configured and has several other kernel debugging settings enabled.
