# $FreeBSD$
# Options set in the build system that affect the kernel somehow.
#
# Define MK_* variables (which are either "yes" or "no") for users
# to set via WITH_*/WITHOUT_* in /etc/src.conf and override in the
# make(1) environment.
# These should be tested with `== "no"' or `!= "no"' in makefiles.
# The NO_* variables should only be set by makefiles for variables
# that haven't been converted over.
#
# Note: bsd.own.mk must be included before the rest of kern.opts.mk to make
# building on 10.x and earlier work. This should be removed when that's no
# longer supported since it confounds the defaults (since it uses the host's
# notion of defaults rather than what's default in current when building
# within sys/modules).
.include <bsd.own.mk>
# These options are used by the kernel build process (kern.mk and kmod.mk)
