I am not really liking kernel 2.6 at least for what i did so I would like to remove it and just have my 2.4.45 kernel how do I do this? I need a newby guide to uninstalling a kernel..

When you installed it, you should have included an entry in your boot menu for the old kernel. Then all you have to do is remove 2.6 from the boot menu. If the 2.4 is not there, look in the /boot directory for it's kernel image file, and add an entry for it in your bootloader.

If you didn't delete them, your old kernels should still be in /boot.

So it's just a matter of editing your /etc/lilo.conf file and referring your old kernel image.

Code:

# Linux bootable partition config begins
image = /boot/vmlinuz
  root = /dev/hda2
  label = Linux
  read-only
image = /boot/vmlinuz-safe
  root = /dev/hda2
  label = Safe
  read-only

Tips are bolded

I have that all done.. I just want to remove the kernel 2.6 for space issues. Not that i have any but incase...

just delete the 2.6 kernel directory in /usr/src

Then delete the kernel image file for 2.6 (it's probably in /boot).

I know theres more places than just that... Isnt there.. I thought i read some thread that theres more places to remove it. preferably id like a command to uninstall it just like you install it like make unintstall or something like that i know that probably isnt a command but i want to do it in the console..

You should remove the modules too, not sure how to do that though (rm -r /lib/modules/2.6 ?). Other than that, that's all you need to remove.

Could you give me a guide to uninstall via konsole? Its just i prefer doing stuff there as i seem to have fewer problems with anything.

Just remove the kernel in boot, source in src and module directory in modules.

remove the kernel (vmlinuz), config, and system.map in /boot
Make sure you have(or get) the old ones that go with your old kernel to put back.
You don't have to have the config file but you do need the system.map
rm -rf /lib/modules/2.6.x
rm -rf /usr/src/2.6.x

Not sure if it works on the kernel but might be worth a try. in the console go inside the folder for the kernel where it was built and type
make uninstall

It works on some software that you build.

On average, the kernel module dir size would be roughly 1MB to 3MB.

An average kernel would be roughly 1MB to 1.5MB in size.

So your space saving would be 5MB at most per kernel build removed.

Are you really that desperate to save space?

A kernel may not be big, and the modules may not be big either, but when you compile the source code directory swells in size dramatically (by 100's of M). So if you're finished compiling stuff, I suggest you run 'make mrproper' to delete the extra stuff, or just delete the whole directory outright.

gnashley · 04-13-2004, 10:22 AM

BTW, the /lib/modules dir is 7-8MB with many modules compiles as in use of bare.i config for standard Slackware kernel-modules package.
