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