Kernel Updates for Stable Releases
Procedures for on-going updates to stable releases of the kernel.
Patches to the kernel not related to security will first appear in <release>-proposed. To use these kernels, you must add a line to your /etc/apt/sources.list file:
deb http://archive.ubuntu.com/ubuntu <release>-proposed main restricted
Currently, there are no linux-meta packages, so updates will have to be manually installed initially. Use this command:
sudo apt-get install linux-image-2.6.15-50-<flavour> linux-restricted-modules-2.6.15-50-<flavour>
Where flavour is one of 386, 686, k7 (for i386 dapper). If you have a different architecture, or are using some other stable release besides dapper, this may change a little. If you do not need linux-restricted-modules, you can choose not to install that. The ABI (50) will remain the same. Other releases will change the kernel version. For example, it will be 2.6.17 for edgy, instead of 2.6.15.
Eventually, stable patches to this kernel will be migrated to the main stable release. Testing (by you) is required to make this happen.
All changes from the stable kernel are listed in the top level changelog entry (there are not multiple entries in the changelog for each upload, just a single rolling entry). When changes are migrated to the stable kernel, they will be removed from the proposed changelog entry.
Every effort will be made to keep the proposed kernel synced with security updates, but do not count on it.
