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.

21# This makefile is simple by design. The FreeBSD make automatically reads
22# the /usr/share/mk/sys.mk unless the -m argument is specified on the
23# command line. By keeping this makefile simple, it doesn't matter too
24# much how different the installed mk files are from those in the source
25# tree. This makefile executes a child make process, forcing it to use
26# the mk files from the source tree which are supposed to DTRT.
27#
28# The user-driven targets (as listed above) are implemented in Makefile.inc1.
29#
30# If you want to build your system from source be sure that /usr/obj has
31# at least 400MB of diskspace available.
32#
33# For individuals wanting to build from the sources currently on their
34# system, the simple instructions are:
35#
36# 1.  `cd /usr/src'  (or to the directory containing your source tree).
37# 2.  `make world'
38#
39# For individuals wanting to upgrade their sources (even if only a
40# delta of a few days):
41#
42# 1.  `cd /usr/src'       (or to the directory containing your source tree).
43# 2.  `make buildworld'
44# 3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is GENERIC).
45# 4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is GENERIC).
46# 5.  `reboot'        (in single user mode: boot -s from the loader prompt).
47# 6.  `mergemaster -p'
48# 7.  `make installworld'
49# 8.  `mergemaster'
50# 9.  `reboot'
51#
52# See src/UPDATING `COMMON ITEMS' for more complete information.
53#
54# If TARGET_ARCH=arch (e.g. ia64, sparc64, ...) is specified you can
55# cross build world for other architectures using the buildworld target,
56# and once the world is built you can cross build a kernel using the
57# buildkernel target.
58#
59# Define the user-driven targets. These are listed here in alphabetical
60# order, but that's not important.
