How to create several custom packaged kernels?

janwil · 2003-10-25 16:10:40

Hi all,

Yesterday I created my own kernel with makepkg and obtained a kernel-*.tar.gz package. After

pacman -U kernel-*.tar.gz

it replaced my old kernel image and (probably) libraries. I realize that this kind of action is a bit dangerous and it is preferrable to have several kernel images living happily next to each other, having lilo or grub for selecting between them.

What should one do in order to get several packages with different kernel images so that they would not conflict?

Thanks,
Jan

danger? I scoff at danger!

err.. I mean.. well if the kernel doesn't work all it takes to fix it is the ftp/boot disks, and when it lets you give the kernel on the disc options type:

arch root=/dev/discs/disc0/part0

or whatever the correct partition is, log in, and then either pacman -S kernel or pacman -A mykernel.pkg.tar.gz

Hapy.

This was posted by orelien a little while ago. I've adjusted it for my needs but here's the original. It probably has to be modified to fit more of what the arch kernel looks like now.
