lines
In the sanitycheck function, treat undefined MKUNPRIVED like "no".
Other uses of MKUNPRIVED should not need this treatment, because
bsd.own.mk sets it to "no" by default, and build.sh uses getmakevar to
pick up that default (but that happens too late for the sanitycheck
function to take advantage of it).

$0: $errmsg
The NetBSD build system requires a shell that supports modern POSIX
features, as well as the "local" keyword in functions (which is a
widely-implemented but non-standardised feature).
Please re-run this script under a suitable shell. For example:
/path/to/suitable/shell $0 ...
The above command will usually enable build.sh to automatically set
HOST_SH=/path/to/suitable/shell, but if that fails, then you may also
need to explicitly set the HOST_SH environment variable, as follows:
HOST_SH=/path/to/suitable/shell
export HOST_SH
\${HOST_SH} $0 ...

exit 1

operation [...]
Build operations (all imply "obj" and "tools"):
build Run "make build".
distribution Run "make distribution" (includes DESTDIR/etc/ files).
release Run "make release" (includes kernels & distrib media).
Other operations:
help Show this message and exit.
makewrapper Create ${toolprefix}make-\${MACHINE} wrapper and ${toolprefix}make.
Always performed.
cleandir Run "make cleandir". [Default unless -u is used]
obj Run "make obj". [Default unless -o is used]
tools Build and install tools.
install=idir Run "make installworld" to \`idir' to install all sets
except \`etc'. Useful after "distribution" or "release"
kernel=conf Build kernel with config file \`conf'
releasekernel=conf Install kernel built by kernel=conf to RELEASEDIR.
installmodules=idir Run "make installmodules" to \`idir' to install all
kernel modules.

rumptest Do a linktest for rump (for developers).
sets Create binary sets in
RELEASEDIR/RELEASEMACHINEDIR/binary/sets.
DESTDIR should be populated beforehand.

# TOOLDIR: TOOLDIR may be affected by settings in /etc/mk.conf, so we
# would like to use getmakevar to get the value of TOOLDIR; but we can't
# use getmakevar before we have an up to date version of nbmake; we
# might already have an up to date version of nbmake in TOOLDIR, but we
# don't yet know where TOOLDIR is.
#
# The default value of TOOLDIR also depends on the location of the top
# level object directory, so $(getmakevar TOOLDIR) invoked before or
# after making the top level object directory may produce different
# results.
#
# Strictly speaking, we should do the following:
#
# 1. build a new version of nbmake in a temporary directory;
# 2. use the temporary nbmake to create the top level obj directory;
# 3. use $(getmakevar TOOLDIR) with the temporary nbmake to
# get the correct value of TOOLDIR;
# 4. move the temporary nbmake to ${TOOLDIR}/bin/nbmake.
#
# However, people don't like building nbmake unnecessarily if their
# TOOLDIR has not changed since an earlier build. We try to avoid
# rebuilding a temporary version of nbmake by taking some shortcuts to
# guess a value for TOOLDIR, looking for an existing version of nbmake
# in that TOOLDIR, and checking whether that nbmake is newer than the
# sources used to build it.

# Run rump build&link tests.
#
# To make this feasible for running without having to install includes and
# libraries into destdir (i.e. quick), we only run ld. This is possible
# since the rump kernel is a closed namespace apart from calls to rumpuser.
# Therefore, if ld complains only about rumpuser symbols, rump kernel
# linking was successful.
#
# We test that rump links with a number of component configurations.
# These attempt to mimic what is encountered in the full build.
# See list below. The list should probably be either autogenerated
# or managed elsewhere; keep it here until a better idea arises.
#
# Above all, note that THIS IS NOT A SUBSTITUTE FOR A FULL BUILD.
