David E. O'Brien ea87b3cb61 Don't install KO's with the "schg" flag. 
We are way too inconsistent with our setting of the "schg" flag, and in
our default install, it doesn't really offer any additional security.

Raw Blame History

# From: @(#)bsd.prog.mk 5.26 (Berkeley) 6/25/91
# $FreeBSD$
#
# The include file <bsd.kmod.mk> handles installing Kernel Loadable Device
# drivers (KLD's).
#
#
# +++ variables +++
#
# CLEANFILES Additional files to remove for the clean and cleandir targets.
#
# DISTRIBUTION Name of distribution. [bin]
#
# KMOD The name of the kernel module to build.
#
# KMODDIR Base path for kernel modules (see kld(4)). [/boot/kernel]
#
# KMODOWN KLD owner. [${BINOWN}]
#
# KMODGRP KLD group. [${BINGRP}]
#
# KMODMODE KLD mode. [${BINMODE}]
#
# LINKS The list of KLD links; should be full pathnames, the
# linked-to file coming first, followed by the linked
# file. The files are hard-linked. For example, to link
# /modules/master and /modules/meister, use:
#
# LINKS= /modules/master /modules/meister
#
# KMODLOAD Command to load a kernel module [/sbin/kldload]
#
# KMODUNLOAD Command to unload a kernel module [/sbin/kldunload]
#
# NOMAN KLD does not have a manual page if set.
#
# PROG The name of the kernel module to build.
# If not supplied, ${KMOD}.o is used.
#
# SRCS List of source files
#
# SUBDIR A list of subdirectories that should be built as well.
# Each of the targets will execute the same target in the
# subdirectories.
#
# SYMLINKS Same as LINKS, except it creates symlinks and the
# linked-to pathname may be relative.
#
# DESTDIR, DISTDIR are set by other Makefiles (e.g. bsd.own.mk)
#
# MFILES Optionally a list of interfaces used by the module.
# This file contains a default list of interfaces.
#
# +++ targets +++
#
# distribute:
# This is a variant of install, which will
# put the stuff into the right "distribution".
#
# install:
# install the program and its manual pages; if the Makefile
# does not itself define the target install, the targets
# beforeinstall and afterinstall may also be used to cause
# actions immediately before and after the install target
# is executed.
#
# load:
# Load KLD.
#
# unload:
# Unload KLD.
#
# bsd.obj.mk: clean, cleandir and obj
# bsd.dep.mk: cleandepend, depend and tags
# bsd.man.mk: maninstall
#
