24Q: How do I fulfill the Linux kernel version requirement?
25A: You need to obtain a recent version of the Linux source code
26 (please look at the README for the exact version), enable the
27 configuration options listed in the README file, install the image,
28 modules and headers, update your bootloader and reboot into the new
29 kernel.
30
31 If you want to compile your own kernel, you can fetch the sources
32 from kernel.org or through your Linux distribution.
33 To install, you need all of the following:
34 make install
35 make modules_install
36 make headers_install INSTALL_HDR_PATH=/usr/local/
