Some systems do this by default everytime a new kernel is created. Sooner or later you run out of space..

Sure. This is my /etc/lilo.conf file. Edit as necessary but you
should get the general idea. Basically you compile the new kernel,
move it to your boot (or root) partition, then add an entry for
the new kernel. At the LILO prompt, I type either "old_kernel" or
"linux". The default, if I don't choose one, is "linux" as defined
by the "label=" line.

boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
default=linux

image=/boot/vmlinuz-2.2.12-20
        label=old_kernel
        initrd=/boot/initrd-2.2.12-20.img
        read-only
        root=/dev/hda8

image=/boot/vmlinuz-2.2.16
        label=linux
        initrd=/boot/initrd-2.2.16.img
        read-only
        root=/dev/hda8

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
