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

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