freebsd/Makefile
Gregory Neil Shapiro b56f8802e5 Despite the fact that it is documented in the handbook, the release notes,
and UPDATING and has been posted to both freebsd-current and
freebsd-stable, users are still not adding the required smmsp user and
group before doing an installworld.  Therefore, don't let users do an
installworld unless they have followed directions.

Add a new installcheck Makefile target which installworld runs before
actually starting the installation.  This target can be used by other parts
of userland as well.  The first addition to the target is to check for the
smmsp user and group if NO_SENDMAIL isn't defined.

Others may add checks to this target as they see fit.

#
# $FreeBSD$
#
# 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.
#
# For novices wanting to build from current sources, the simple instructions
# are:
#
# 1. Ensure that your /usr/obj directory has at least 260 Mb of free space.
# 2. `cd /usr/src' (or to the directory containing your source tree).
# 3. `make world'
#
# Be warned, this will update your installed system, except for configuration
# files in the /etc directory and for the kernel. You have to do those manually.
#
# If at first you're a little nervous about having a `make world' update
# your system, a `make buildworld' will build everything in the /usr/obj
# tree without touching your installed system. To be of any further use
# though, a `make installworld' is required.
#
# 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.
#
# ----------------------------------------------------------------------------
#
# 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.
