 |
|
Hi,
I have several custom kernel modules (nvidia-kernel, ipp2p, bluetooth-alsa), and, each time I build a new kernel, I had to re-emerge them manually (and I had to remember which one were installed).
So I created a small script to rebuild kernel modules (I called it "eupdate_modules"):
| Code: | #!/bin/bash
echo "Searching for ebuilds containing files in /lib/modules..."
LIST=`grep " /lib/modules/$KERNEL" /var/db/pkg/*/*/CONTENTS | grep ".ko" | sed -e 's/^\/var\/db\/pkg\/\(.*\)\/CONTENTS.*$/>=\1/'`
CMD="emerge -a"
for i in $LIST; do
CMD="$CMD $i"
done
echo "Running \"$CMD\"..."
exec $CMD |
The general procedure to build a new kernel is the following:
| Code: | cd /usr/src
rm linux
ln -s linux-2.6.your-version linux (This is important because most ebuilds won't build against the correct kernel if you don't set the /usr/src/linux symlink)
cd linux
(configure your kernel and install it)
/path_to/eupdate_modules (my script)
(reboot)
|
I don't know if it could be integrated in genkernel (I build my kernels manually).
I hope it'll be useful for some of you, and if you think it is worth a HOWTO in the Wiki tell me so and I'll create a page. |
