I have had someone come to my website looking for help on how to copy an Ubuntu kernel over to a Gentoo installation. This is not too hard to do. Let us say the kernel is version 2.6.35-14-generic. Then you will need to copy the /lib/modules/2.6.35-14-generic folder into the /lib/modules folder on your Gentoo installation. Then you will need to copy the vmlinuz-2.6.35-14-generic kernel image and the initrd.img-2.6.35-14-generic files over to the /boot folder on your Gentoo installation. As well as the System.map-2.6.35-14-generic file which also goes into /boot. Then you will need to update the boot loader and the files you have added will be added to the Gentoo boot loader.
I have done this myself and this does work.
Information on the Gentoo bootloader here: gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=10.
I am a computer enthusiast that has always been interested in maintaining and upgrading computer hardware. I was born on a farm and lived there for 13 years before moving into town. I was always interested in technology and my father always gave me good encouragement for developing my knowledge and interest in tinkering with computers. He was using a computer on the farm but that was in the very late 80`s and late 90`s. Seeing what a computer could do always fascinated me and then I knew that is what I wanted to do. The first time I used Linux was Red Hat 6.2 installed off a single CDROM and I was amazed that you did not need to install any more drivers on my old Intel Celeron machine to be able to enjoy a nice 24BPP desktop and use the GIMP to edit photos and enjoy playing the old Linux games like Xbill. Then a while later I tried Mandrake Linux 9.2 and I was hooked. It came with so much software and was very easy to use as well. Then Mandrake Linux 10 and on through FreeBSD, Debian 3.0, Debian 3.1 Suse Linux 9.2, Suse 10 and onto the Ubuntu distributions although I am using Fedora Core 15 and the Gnome 3 desktop at the moment.
Sorry about the formatting, I typed this into WordPress on my ‘phone.
