It is possible to patch a kernel to the newest Linux kernel version as opposed to downloading the
entire source code. This choice can be beneficial for those who are not using a high-speed
broadband connection. (A typical compressed kernel source file is nearly 30MB for a download
time of about 10 minutes on a 512Kb DSL connection; adjust accordingly for your connection.)
Whether you are patching existing sources or downloading the full source, the end results will be
identical.Patching the kernel is not a mindless task. It requires the user to retrieve all patches from her
current version to the version she wants to upgrade to. For example, if you are currently running
2.6.1 (and have those sources) and want to upgrade to 2.6.8, you must retrieve the 2.6.2 and
2.6.3 patch sets, and so on. Once downloaded, these patches must be applied in succession to
upgrade to 2.6.8. This is more tedious than downloading the entire source, but useful for those
who keep up with kernel hacking and want to perform incremental upgrades to keep their Linux
kernel as up-to-date as possible.
To patch up to several versions in a single operation, you can use the patch-kernel script located
in the kernel source directory for the kernel version you currently use. This script applies all
necessary version patches to bring your kernel up to the latest version.
The format for using the patch-kernel script looks like this:
patch-kernel source_dir patch_dir stopversion
