I'm running Fedora Core 2 and since installation the kernel has been upgraded twice (I keep her up to date). Whenever I occasionally have to reboot it shows all the previous kernels and which one I'd like to boot. I always select the most current one of course. I'm guessing there is a way to remove those others from the list? I have looked into it, but haven't tried anything as I fear of messing something up.

yeah, there is....the way depends a bit on whether you use grub or lilo or what as your bootloader. basically:

1) delete the old kernel and System.map from /boot (and if there are some other old files that you don't need)
2) edit the bootloader's config, remove the old kernel entries and save

if you use grub as your bootloader, simply edit /boot/grub/menu.lst (or grub.conf?) and remove the sections that deal with old kernels. then save it and you're fine. with lilo you have to remove the old kernel sections from lilo's config file and then RUN LILO ONCE so the changes are actually "saved" and you won't get problems when rebooting....grub is simpler

Excellent.

Thanks again.
