Kernel-headers packages to use with crouton

This is a ubuntu/debian ppa for chromebook kernel headers.

Currently supported:

• Kernel 3.4.0 Architecture arm, i386 and am64 ==> These all need testing.
• Kernel 3.8.11 Architecture arm, i386 and am64 ==> amd64 is tested. i386 and arm needs testing.
• Kernel 3.10.18 Architecture arm and amd64 ==> amd64 is tested. i386 and arm needs testing.

For being able to load modules outside /lib/modules from chromeos we will need to disable module_locking. This can be done by changing the kernel flags. I wrote a little script that does this for you and also has the option to revert the changes.
Open a crosh shell and follow on screen instructions:

$ cd ~/Downloads
$ wget https://raw.githubusercontent.com/divx118/crouton-packages/master/change-kernel-flags
$ sudo sh ~/Downloads/change-kernel-flags

When running sudo sh ~/Downloads/change-kernel-flags -h it will give you the usage. When you want to revert the changes so put back a backup kernel use -r
sudo sh ~/Downloads/change-kernel-flags -r

Note: You will need to repeat the above steps after each chromeos update.

Open a shell in your chroot:

$ cd ~
$ wget https://raw.githubusercontent.com/divx118/crouton-packages/master/setup-headers.sh
$ sudo sh setup-headers.sh

This script will:

• add my signing key with which the packages are signed.
• add the ppa to the sources.list.d
• install linux-headers-
• install linux-image-
• add a rc.local script to load vboxdrv modules on entering the chroot if they are available.

Kernel headers are build according to this guide https://github.com/dnschneid/crouton/wiki/Build-kernel-headers-and-install-Virtualbox-(x86) kernel headers for arm are cross compiled.
