Hi,

I started using Linux back in January and I have been running my media PC and HLDS ever since with only a few reboots.

[Boring]But then I tried to get TV out working for my graphics card and I stuffed up, and I realised I formatted in a poor way, with /home taking up a large part of my hard drive (when I really want my media drive as the largest). Anyhoo long story short I was going to do a reinstall of all things Linux.[/Boring]

Now, I upgraded my kernel to 2.6.15 and have had no troubles, but I kept 2.4.31 (I think) on the system, and I can boot with that one in LILO. The question is, when I install this time, how can I remove all the old stuff once it is working. I have my install/upgrade thing down pat (with lots of help from here), but I have never removed the old kernel too.

Any help would be apprieciated

When you remove the /usr/src/linux dir, you are sorta getting rid of some of the old kernal. All you have to do is remove the listing from your grub/lilo config file, then just remove all old stuff to do with the kernel amd your done.

Because Linux is a modular OS, you can simply remove old kernel from /boot (should be named vmlinuz) and its sources from /usr/src (linux-2.4.31).

The above posts are correct.

To remove a kernel from your computer:

1) Delete the appropriate vmlinuz from /boot (and the symlinks, depending on your config)
2) Remove the entry from /etc/lilo.conf
3) Get rid of /lib/modules/Kenrel_version

I would say, though, that it is a good idea (especially when learning) to leave all that stuff alone. You can always boot into the stock 2.4 series kernel when you mess up.
