Genkernel applied to the Debian sources
A good candidate to quickly start with Genkernel is the Debian kernel (sys-kernel/debian-sources) mainly because:
- Configuration files are available for the various platforms supported by the Derbian project
- The configuration makes an intensive use of putting features in modules
First step
The first step is to emerge:
- The Debian sources
- Genkernel itself
This is achieved with:
# emerge sys-kernel/debian-sources sys-kernel/genkernel
Once the Debian kernel sources are deployed, you should find a directory named linux-debian-version (e.g. linux-debian-2.6.32.30) under /usr/src. Update your the linux symlink to point on this directory:
# cd /usr/src # rm linux # ln -s linux-debian-2.6.32.30 linux
Second step
If is now time to download the configuration file. For this tutorial we will use a configuration file for AMD64 as published by the Debian project, if you plan to use the Debian kernel you are advised to review it adjust it to your needs although it is tailored for a vast range of machines.
# cd linux # wget http://merkel.debian.org/~jurij/2.6.32-30/amd64/config-2.6.32-5-amd64.gz # gunzip config-2.6.32-5-amd64.gz # cp config-2.6.32-5-amd64.gz .config
