10The Makefile in this directory supports a number of targets for
11building components (or all) of the FreeBSD source tree, the most
12commonly used one being ``world'', which rebuilds and installs
13everything in the FreeBSD system from the source tree except the
14kernel, the kernel-modules and the contents of /etc.  The ``world''
15target should only be used in cases where the source tree has not
16changed from the currently running version.  See:
17http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html
18for more information, including setting make(1) variables.
19
20The ``buildkernel'' and ``installkernel'' targets build and install
21the kernel and the modules (see below).  Please see the top of
22the Makefile in this directory for more information on the
23standard build targets and compile-time flags.
24
25Building a kernel is a somewhat more involved process, documentation
26for which can be found at:
27   http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html
28And in the config(8) man page.
29Note: If you want to build and install the kernel with the
30``buildkernel'' and ``installkernel'' targets, you might need to build
31world before.  More information is available in the handbook.
32
33The sample kernel configuration files reside in the sys/<arch>/conf
34sub-directory (assuming that you've installed the kernel sources), the
35file named GENERIC being the one used to build your initial installation
36kernel.  The file NOTES contains entries and documentation for all possible
37devices, not just those commonly used.  It is the successor of the ancient
38LINT file, but in contrast to LINT, it is not buildable as a kernel but a
39pure reference and documentation file.
