Most of that script isn't needed.

If I do "make install" after "make modules_install" it will copy the kernel to /boot. It'll also make symlinks called /boot/vmlinuz and /boot/vmlinuz.old

/boot/vmlinuz will now point to the kernel you just installed. And if you already had a /boot/vmlinuz previously, vmlinuz.old will now point to that kernel old kernel.

And the nvidia-kernel and glx steps aren't needed because this means you'd have to do that for each kernel modules. Instead you do:
(before running the script) do "emerge module-rebuild"
Then in the script do "module-rebuild rebuild"

I will translate this thread for the French Forum. Is there any objections before I start ?

To Wynn and all other contributors of this FAQ! *bows to the gods*

Thank you! I'll be giving this another shot in the next couple of days.
The tips and tricks you showed us will definately help out!

Although... I don't recall who said it, someone made mention with
machine specs being what they are today, having a lean,
mean kernel build isn't as important as what it used to be.

Being a nOOb at kernel configuring.. it's something I aim to do regardless!

PS. The flash at the end of the FAQ was pretty cool.
Kinda fast for us old farts though... ;)

Just a quick note, the Kernel configuration slideshow has moved to a different url. You can find it at this URL:

http://tutorialmasters.com/node/3


Sorry for anyone who may have missed it, but moved my site to drupal so the address had to change.

Update: Fixed with a 301 redirect/ :)

Here is something i use for my kernel updates...
Code:
#!/bin/bash
LOADER_ROOT_PARTITION="hd0,6"
KERNEL_PARAMETERS="root=/dev/hda7 vga=0x315 quiet"
if [[ -d /usr/src/linux ]];then
        echo "Cleaning the old sources"
else
        echo "You don't have a symbolic link or a directory /usr/src/linux and the script depends on that"
        exit 3
fi
#Get the VERSION from the symbolic link
VERSION=$(readlink /usr/src/linux)
#Entering the sources dir
cd /usr/src/linux
make mrproper
if [[ -f /proc/config.gz ]];then
        zcat /proc/config.gz > ./.config
else
        "There isn't /proc/config.gz and the script depend on it"
        eixt 3
fi
#If you want to edit the old options, comment "make oldconfig" and uncomment "make menuconfig"
###############################################################################
#make menuconfig
make oldconfig
make -j2
make modules_install
mv /usr/src/linux/arch/i386/boot/bzImage /boot/"${VERSION%/}"
#Making the menu.lst configuration; some versions of grub have grub.conf instead so you can change it if
#there isn't a symbolic link(there should be).
#TODO: Make a sed hack that edit the default parameter and put the new section as default
#section_number=$(grep title /boot/grub/menu.lst | wc -l)
echo "" >> /boot/grub/menu.lst
echo "title=${VERSION%/}" >> /boot/grub/menu.lst
echo "root(${LOADER_ROOT_PARTITION})" >> /boot/grub/menu.lst
echo "kernel /boot/${VERSION%/} ${KERNEL_PARAMETERS}" >> /boot/grub/menu.lst
If a sed master can make the sed command for the section_number implementation i would be glad to see it :)

P.S. This is for Grub ^_^

Why do you use this command ? :
Code:
make -j2


If you have MAKEOPTS= '-j2' in your /etc/make.conf, you don't have to pass this variable to make.

Actually you have to ;) /etc/make.conf is only "sourced" by portage, as far as i know.

Just a tip: make sure you build your hard drive driver into the kernel as well as the driver for your motherboard's SATA/PATA/ATA driver. It cause me lots of headaches trying to figure out what was wrong before seeing that.

This is a great how-to for a beginner. Thank's to d2_racing who dropped me an e-mail to tell me about its existence.

As I'm rewriting French installation documentation on Gentoo-Québec web site (from PDF to Mediawiki format), this wynn's how-to will greatly help me. Most of all, my approach is quite similar to the one of this tutorial. Can you read French ? So just look at this wiki still in the work :

http://gentoo-quebec.org/wiki/index.php/100-Installation:Gentoo_classique_unstable#Configuration_du_noyau

I have a question somehow. The how-to shows how to use udevinfo. It seems that udevinfo and other commands such like undevmonitor and the likes are now replaced by udevadm. Is it possible that someone updates the tutorial in order to tell about the usage of udevadm ?

Quote:
To find the chipset driver (or drivers) for /dev/sda, runCode:
udevinfo -a -p /sys/block/sda | grep DRIVERS


Sorry, this command does not work.
Code:
# udevinfo -a -p /sys/block/sdb | grep DRIVERS
-su: udevinfo: command not found
#


Am I doing something wrong, or is it time to update this helpful guide?

Most udev commands have moved to udevadm. So, now you should run
Code:
udevadm info ...
