Implement the checks for required_* objects as two functions, one to be run before precmd and the other after it. They get the current rc command as an argument so they can choose what requirement tests to perform. As of now, only "start" needs such tests. Implement a new requirement variable, required_modules. It can list kernel modules that need to be loaded after start_precmd indicated success. Each name in the list can be just "file", or "file:module", or "file~regex". This will allow us to remove a lot of duplicated code from rc.d scripts. Perform the checks not only for the default start method, but for any method. This allows for more flexibility and fixes a few rc.d scripts (namely newsyslog, pf, sendmail) that rely on a required_* variable while providing a non-default start method. To be able to call the new check_required* functions naturally, remove lots of crufty duplicated code pieces from run_rc_command and replace each of them by a call to the helper function providing a single corrected instance of the respective code snippet. Now run_rc_command isn't as scary as it used to be, and it even appears to have quite a nice logic that was obscured by the old crufty code. In the default handler for restart, run start from a subshell to protect global varibles, e.g., _postcmd, from modification by the start handler. This enables using restart_postcmd.

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.
