     50        Building the linux kernel for the first time is one of the most
     51        challenging tasks in LFS.  Getting it right depends on the specific
     52        hardware for the target system and your specific needs. There are
     53        almost 12,000 configuration items that are available for the kernel
     54        although only about a third of them are needed for most computers. The
     55        LFS editors recommend that users not familiar with this process follow
     56        the procedures below fairly closely.  The objective is to get an
     57        initial system to a point where you can log in at the command line when
     58        you reboot later in <xref linkend="ch-finish-reboot"/>.  At his point
     59        optimization and customization is not a goal.

     67        url="&anduin-sources;/kernel-nutshell/"/>.
     68        These references are a bit
     69        dated, but still give a reasonable overview of the process.
