From the original OpenBSD commit message: restore the traditional behavior of -f implying -a; apparently Keith Bostic forgot to restore it when the -f flag was put back on 2nd of September 1989, after being removed on 16th of August as a consequence of issues getting it working over NFS, so deviation from traditional UNIX behavior in all BSDs looks like an historical accident; as a side effect, this change accommodates behavior of this option to IEEE Std 1003.1-2008 (``POSIX.1''). joint work with jmc@ (who found the inaccuracy in our implementation), schwarze@ (who provided a detailed tracking of historical facts) and millert@ Submitted by: Igor Sobrado Discussed with: mckusick Obtained from: OpenBSD project MFC after: 2 weeks

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 ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. 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/doc/en_US.ISO8859-1/books/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 might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/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.
