4# The user-driven targets are:
5#
6# universe            - *Really* build *everything* (buildworld and
7#                       all kernels on all architectures).
8# buildworld          - Rebuild *everything*, including glue to help do
9#                       upgrades.
10# installworld        - Install everything built by "buildworld".
11# world               - buildworld + installworld.
12# buildkernel         - Rebuild the kernel and the kernel-modules.
13# installkernel       - Install the kernel and the kernel-modules.
14# reinstallkernel     - Reinstall the kernel and the kernel-modules.
15# kernel              - buildkernel + installkernel.
16# update              - Convenient way to update your source tree (cvs).
17# upgrade             - Upgrade a.out (2.2.x/3.0) system to the new ELF way
18# most                - Build user commands, no libraries or include files.
19# installmost         - Install user commands, no libraries or include files.
20# aout-to-elf         - Upgrade a system from a.out to elf format (see below).
21# aout-to-elf-build   - Build everything required to upgrade a system from
22#                       a.out to elf format (see below).
23# aout-to-elf-install - Install everything built by aout-to-elf-build (see
24#                       below).
25# move-aout-libs      - Move the a.out libraries into an aout sub-directory
26#                       of each elf library sub-directory.
27#
28# This makefile is simple by design. The FreeBSD make automatically reads
29# the /usr/share/mk/sys.mk unless the -m argument is specified on the
30# command line. By keeping this makefile simple, it doesn't matter too
31# much how different the installed mk files are from those in the source
32# tree. This makefile executes a child make process, forcing it to use
33# the mk files from the source tree which are supposed to DTRT.
34#
35# The user-driven targets (as listed above) are implemented in Makefile.inc1.
36#
37# If you want to build your system from source be sure that /usr/obj has
38# at least 400MB of diskspace available.
39#
40# For individuals wanting to build from the sources currently on their
41# system, the simple instructions are:
42#
43# 1.  `cd /usr/src'  (or to the directory containing your source tree).
44# 2.  `make world'
45#
46# For individuals wanting to upgrade their sources (even if only a
47# delta of a few days):
48#
49# 1.  `cd /usr/src'       (or to the directory containing your source tree).
50# 2.  `make buildworld'
51# 3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is GENERIC).
52# 4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is GENERIC).
53# 5.  `reboot'        (in single user mode: boot -s from the loader prompt).
54# 6.  `mergemaster -p'
55# 7.  `make installworld'
56# 8.  `mergemaster'
57# 9.  `reboot'
58#
59# See src/UPDATING `COMMON ITEMS' for more complete information.
60#
61# If TARGET_ARCH=arch (e.g. ia64, sparc64, ...) is specified you can
62# cross build world for other architectures using the buildworld target,
63# and once the world is built you can cross build a kernel using the
64# buildkernel target.

67#
68#           Upgrading an i386 system from a.out to elf format
69#
70#
71# The aout->elf transition build is performed by doing a `make upgrade' (or
72# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed
73# by a `make aout-to-elf-install', depending on user preference.
74# You need to have at least 320 MB of free space for the object tree.
75#
76# The upgrade process checks the installed release. If this is 3.0-CURRENT,
77# it is assumed that your kernel contains all the syscalls required by the
78# current sources.
79#
80# The upgrade procedure will stop and ask for confirmation to proceed
81# several times. On each occasion, you can type Ctrl-C to abort the
82# upgrade.  Optionally, you can also start it with NOCONFIRM=yes and skip
83# the confirmation steps.
