New MINIMAL kernel config. The goal with this configuration is to

only compile in those options in GENERIC that cannot be loaded as
modules. ufs is still included because many of its options aren't
present in the kernel module. There's some other exceptions documented
in the file. This is part of some work to get more things
automatically loading in the hopes of obsoleting GENERIC one day.

+# MINIMAL -- Mostly Minimal kernel configuration file for FreeBSD/amd64
+#
+# Many definitions of minimal are possible. The one this file follows is
+# GENERIC, minus all functionality that can be replaced by loading kernel
+# modules.
+#
+# Exceptions:
+# o While UFS is buildable as a module, the current module lacks
+#   some features (ACL, GJOURNAL) that GENERIC includes.
+# o acpi as a module has been reported flakey and not well tested, so
+#   is included in the kernel.
+# o random is included due to uncertaty...
+# o Many networking things are included
+#
+# For now, please run changes to these list past imp@freebsd.org
+#
+# For more information on this file, please read the config(5) manual page,
+# and/or the handbook section on Kernel Configuration Files:
+#
+#    http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-config.html
+#
+# The handbook is also available locally in /usr/share/doc/handbook
+# if you've installed the doc distribution, otherwise always see the
+# FreeBSD World Wide Web server (http://www.FreeBSD.org/) for the
+# latest information.
+#
+# An exhaustive list of options and more detailed explanations of the
+# device lines is also present in the ../../conf/NOTES and NOTES files.
+# If you are in doubt as to the purpose or necessity of a line, check first
+# in NOTES.
