# The user-driven targets are:
#
# buildworld - Rebuild *everything*, including glue to help do
# upgrades.
# installworld - Install everything built by "buildworld".
# world - buildworld + installworld.
# buildkernel - Rebuild the kernel and the kernel-modules.
# installkernel - Install the kernel and the kernel-modules.
# reinstallkernel - Reinstall the kernel and the kernel-modules.
# kernel - buildkernel + installkernel.
# update - Convenient way to update your source tree (cvs).
# upgrade - Upgrade a.out (2.2.x/3.0) system to the new ELF way
# most - Build user commands, no libraries or include files.
# installmost - Install user commands, no libraries or include files.
# aout-to-elf - Upgrade an system from a.out to elf format (see below).
# aout-to-elf-build - Build everything required to upgrade a system from
# a.out to elf format (see below).
# aout-to-elf-install - Install everything built by aout-to-elf-build (see
# below).
# move-aout-libs - Move the a.out libraries into an aout sub-directory
# of each elf library sub-directory.
#
# This makefile is simple by design. The FreeBSD make automatically reads
# the /usr/share/mk/sys.mk unless the -m argument is specified on the
# command line. By keeping this makefile simple, it doesn't matter too
# much how different the installed mk files are from those in the source
# tree. This makefile executes a child make process, forcing it to use
# the mk files from the source tree which are supposed to DTRT.
#
# The user-driven targets (as listed above) are implemented in Makefile.inc1.
#
# If you want to build your system from source be sure that /usr/obj has
# at least 400MB of diskspace available.
#
# For individuals wanting to build from the sources currently on their
# system, the simple instructions are:
#
# 1. `cd /usr/src' (or to the directory containing your source tree).
# 2. `make world'
#
# For individuals wanting to upgrade their sources (even if only a
# delta of a few days):
#
# 1. `cd /usr/src' (or to the directory containing your source tree).
# 2. `make buildworld'
# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
# 5. `reboot' (in single user mode: boot -s from the loader prompt).
# 6. `mergemaster -p'
# 7. `make installworld'
# 8. `mergemaster'
# 9. `reboot'
#
# See src/UPDATING `COMMON ITEMS' for more complete information.
#
# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will
# update the legacy support for aout. This includes all libraries, ld.so
# and boot objects. This part of build should be regarded as
# deprecated and you should _not_ expect to be able to do this past the
# release of 4.0. You have exactly one major release to move entirely
# to elf.
#
# If TARGET_ARCH=arch (e.g. ia64, sparc64, ...) is specified you can
# cross build world for other architectures using the buildworld target,
# and once the world is built you can cross build a kernel using the
# buildkernel target.
#
# ----------------------------------------------------------------------------
#
# Upgrading an i386 system from a.out to elf format
#
#
# The aout->elf transition build is performed by doing a `make upgrade' (or
# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed
# by a `make aout-to-elf-install', depending on user preference.
# You need to have at least 320 Mb of free space for the object tree.
#
# The upgrade process checks the installed release. If this is 3.0-CURRENT,
# it is assumed that your kernel contains all the syscalls required by the
# current sources.
#
# The upgrade procedure will stop and ask for confirmation to proceed
# several times. On each occasion, you can type Ctrl-C to abort the
# upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip
# the confirmation steps.
#
# At the end of the upgrade procedure, /etc/objformat is created or
# updated to contain OBJFORMAT=elf. From then on, you're elf by default.
