luigi fd0ff82a6c Add a readonly sysctl variable of type string, kern.bootp_cookie,
which is initialized with whatever string a dhcp/bootp server passes
as vendor tag 134.
There is no standard tag that I know with this information, and
no vendor-defined tag that applies to FreeBSD that I could find
doing the same thing.

The intended use is to pass information to userland for run-time
configuration of a diskless client without having to run a bootp/dhcp
client for the third time (after the one in pxeboot/etherboot, and
the one in the kernel bootp), also because these clients generally
screwup the interface configuration, which is not exactly what you
want when you have your disks nfs-mounted.

Manpage update to follow soon.

This is the top level of the FreeBSD source directory.  This file
was last revised on:
$FreeBSD$

For copyright information, please see the file COPYRIGHT in this
directory (additional copyright information also exists for some
sources in this tree - please see the specific source directories for
more information).

The Makefile in this directory supports a number of targets for
building components (or all) of the FreeBSD source tree, the most
commonly used one being ``world'', which rebuilds and installs
everything in the FreeBSD system from the source tree except the
kernel, the kernel-modules and the contents of /etc.  The
``buildkernel'' and ``installkernel'' targets build and install
the kernel and the modules (see below).  Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.

Building a kernel is a somewhat more involved process, documentation
for which can be found at:
   http://www.freebsd.org/handbook/kernelconfig.html
And in the config(8) man page.
Note: If you want to build and install the kernel with the
``buildkernel'' and ``installkernel'' targets, you have to build
world before.  More information is available in the handbook.

The sample kernel configuration files reside in the sys/i386/conf
sub-directory (assuming that you've installed the kernel sources), the
file named GENERIC being the one used to build your initial installation
kernel.  The file NOTES contains entries and documentation for all possible
devices, not just those commonly used.  It is the successor of the ancient
LINT file, but in contrast to LINT, it is not buildable as a kernel but a
pure reference and documentation file.
