1# $FreeBSD$ 2# 3# NOTES -- Lines that can be cut/pasted into kernel and hints configs. 4# 5# Lines that begin with 'device', 'options', 'machine', 'ident', 'maxusers', 6# 'makeoptions', 'hints', etc. go into the kernel configuration that you 7# run config(8) with. 8# 9# Lines that begin with 'hint.' are NOT for config(8), they go into your 10# hints file. See /boot/device.hints and/or the 'hints' config(8) directive. 11# 12# Please use ``make LINT'' to create an old-style LINT file if you want to 13# do kernel test-builds. 14# 15# This file contains machine independent kernel configuration notes. For 16# machine dependent notes, look in /sys/<arch>/conf/NOTES. 17# 18 19# 20# NOTES conventions and style guide: 21# 22# Large block comments should begin and end with a line containing only a 23# comment character. 24# 25# To describe a particular object, a block comment (if it exists) should 26# come first. Next should come device, options, and hints lines in that 27# order. All device and option lines must be described by a comment that 28# doesn't just expand the device or option name. Use only a concise 29# comment on the same line if possible. Very detailed descriptions of 30# devices and subsystems belong in man pages. 31# 32# A space followed by a tab separates 'options' from an option name. Two 33# spaces followed by a tab separate 'device' from a device name. Comments 34# after an option or device should use one space after the comment character. 35# To comment out a negative option that disables code and thus should not be 36# enabled for LINT builds, precede 'options' with "#!". 37# 38 39# 40# This is the ``identification'' of the kernel. Usually this should 41# be the same as the name of your kernel. 42# 43ident LINT 44 45# 46# The `maxusers' parameter controls the static sizing of a number of 47# internal system tables by a formula defined in subr_param.c. 48# Omitting this parameter or setting it to 0 will cause the system to 49# auto-size based on physical memory. 50# 51maxusers 10 52 53# To statically compile in device wiring instead of /boot/device.hints 54#hints "LINT.hints" # Default places to look for devices. 55 56# Use the following to compile in values accessible to the kernel 57# through getenv() (or kenv(1) in userland).

Use 'make install.debug' to install the debug kernel 74# but that isn't normally necessary as the debug symbols are not loaded 75# by the kernel and are not useful there anyway. 76# 77# KERNEL can be overridden so that you can change the default name of your 78# kernel. 79# 80# MODULES_OVERRIDE can be used to limit modules built to a specific list. 81# 82makeoptions CONF_CFLAGS=-fno-builtin #Don't allow use of memcmp, etc. 83#makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols 84#makeoptions KERNEL=foo #Build kernel "foo" and install "/foo" 85# Only build ext2fs module plus those parts of the sound system I need. 86#makeoptions MODULES_OVERRIDE="ext2fs sound/sound sound/driver/maestro3" 87makeoptions DESTDIR=/tmp 88 89# 90# FreeBSD processes are subject to certain limits to their consumption 91# of system resources.

In 1234# earlier versions the unit numbers were assigned in the order that 1235# the devices were probed on the SCSI bus. This means that if you 1236# removed a disk drive, you may have had to rewrite your /etc/fstab 1237# file, and also that you had to be careful when adding a new disk 1238# as it may have been probed earlier and moved your device configuration 1239# around.
