.: Advanced Linux Networking :.

The preceding discussion has covered the most important options you'll encounter in configuring a kernel to use the networking protocols on your network, and the hardware you use to connect a computer to that network. The process of compiling the kernel, however, is another matter, and one that's not, strictly speaking, a networking task. Nonetheless, this task is important if you need to recompile your kernel to add or delete support for specific network features, so this section provides an overview of some of the decisions and procedures involved.

Don't adjust only the options described earlier in this chapter and then compile your kernel. Although they're beyond the scope of this book, kernel options relating to features like EIDE controllers, SCSI host adapters, and disk filesystems are critically important for a functioning Linux computer. If you incorrectly configure these features, your computer may not boot at all, or it may perform in a substandard way (for instance, with very poor disk speed). These options are discussed in documents such as the Linux Kernel HOWTO at http://www.linuxdoc.org/HOWTO/Kernel-HOWTO.html (among many other places) and many general Linux books.
