Question 3

When should you patch a kernel? How is this accomplished?

Accepted Answer

To install a more current Linux kernel version, you normally download the source code for that kernel and place it in a directory that will be referenced by /usr/src/linux . If the /usr/src/linux directory already contains the source code for the current kernel, you can instead choose to download and apply patch files to this source code to change it into the desired version. Patches are not cumulative; to patch the Linux kernel version 2.6.7 to 2.6.9, you must apply the Linux kernel patches 2.6.8 and 2.6.9. Patches are typically distributed in compressed form; to apply a patch, simply download and uncompress the patch file into the /usr/src/linux directory and execute the patch command. To execute a kernel patch, you can type patch . When all patches have been applied, you can compile the kernel.
