Gentoo Kernel Upgrade notes

Probably not relevant to anyone other than myself.

check portage version (you are ok unless you have a 2.0.x.x version; see elsewhere for help with that):

# emerge portage -vpThese are the packages that would be merged, in order:
Calculating dependencies… done!
[ebuild   R   ] sys-apps/portage-2.1.4.4  USE="-build -doc -epydoc (-selinux)" LINGUAS="-pl" 0 kB
Total: 1 package (1 reinstall), Size of downloads: 0 kB

sync the portage tree:

# emerge --sync

check the available kernel source:

# emerge gentoo-sources -vpThese are the packages that would be merged, in order:
Calculating dependencies… done!
[ebuild   R   ] sys-kernel/gentoo-sources-2.6.25-r4  USE="-build -symlink*" 0 kB
Total: 1 package (1 reinstall), Size of downloads: 0 kB

if it looks right, do it:

# USE=symlink emerge gentoo-sources

optionally be fussy about the version number:

# USE=symlink emerge =gentoo-sources-2.6.25-r7

get the config from the previous verion:

# mount /boot
# cd /usr/src/linux
# cp /boot/config-2.6.25-gentoo-r4 .config

update the config, this asks you the questions that are not satisfied from the previous configuration, you can usually just accept the defaults unless something is really obviously wrong:

# make oldconfig

build it

# make
# make modules_install

install it

# cp arch/x86_64/boot/bzImage /boot/kernel-2.6.25-gentoo-r7
# cp .config /boot/config-2.6.25-gentoo-r7

fix /boot/grub/grub.conf to include your new kernel, and if you feel lucky, make it the default
done!
