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