attempting to export the non-root of a filesystem with -alldirs. This pilot error seems to be very common, and the "could not remount" error message doesn't give much hints about the real reason. See the old PR below for an example. While i was at it, make it possible to entirely omit the often annoying error message in that case by specifying the "quiet" exports flag. This allows to specify something like /cdrom -alldirs,ro,quiet <where to export to> which will silently fail if nothing is mounted under /cdrom, but do the rigth thing as soon as you mount something. While doing this, i've put the embedded example in the exports(5) man page into a subsection of its own as it ought to be. Thanks for Paul Southworth for reminding me about this problem.

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 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.
