emerge update world gave me a new kernel... now what?

[N715DP]

Hello all, sorry if this has been covered before, if it has, a pointer to the previous post would be greatly appreciated.

I did a world update after getting Gentoo-2.6.9-r1 up and running and I noticed that it gave me a new kernel of Gentoo-2.6.9-r9.

How do I go about setting up for the new kernel? Is it already compiled and ready to go based on the make menuconfig that I did when installing the -r1 kernel?

Hi,
if you emerged the kernel -r9 then it should be in /usr/src/
you can copy the .config from your old kernel, gentoo-2.6.9-r1/.config and move it over the new directory. like so:
As root:
cp /usr/src/linux/.config /usr/src/Gentoo-2.6.9-r9/.config

then change directory to the new kernel and type "make oldconfig"
...it will prompt you for the new options. its safe to say N.

type: make && make modules_install

mount /boot
mv arch/i386/boot/bzImage /boot/gentoo-2.6.9-r9
( moves the kernel to the boot partition )

edit the symlink from linux -> gentoo-2.6.9-r9

edit your boot loader and your set to reboot.

You should read some docs how to compile a kernel

Don't forget to make sure the /usr/src/linux symlink points to your new kernel as well.

Thanks for the info, I'll give it a shot now.

I did read through everythig I could find (I still say Gentoo documentation kicks major ***) but I wanted to check with someone in pseudo-real-time to make sure I didn't miss anything (like I know I would have missed the sym-link).

I'll post back with the results, thanks again!

hmmm... there is no bzImage...

Thoughts?

Think I got it...

had to change the symlink and then do make && make modules_install (which is going now)... hope this works.

NOTE: if everything works for you it might not be needed to install the new kernel. I tend to keep fairly up to date (upgrade the kernel once a month..), but can't be bothered to use a new one everyime it's released

thanks for all the help guys, currently in the new kernel and working like a champ.
