LinuxDevices.com has published
an article by veteran Linux author William von Hagen about changes to the configuration process in the 2.6 Linux kernel. The article is the first in a series of articles that will discuss using the Linux kernel and device drivers, etc., in embedded devices. However, the article is generally relevant to servers and desktops, too. Be aware, the author did not mention on the "migration from kernel 2.4" section of the article that you will need to
download the latest module-init-tools (and the new 'udev', 'hotplug' packages
if you were using these too) in order to fully & correctly migrate to 2.6.
