usage()
{
cat <<EOF
Usage: ${0##*/} [OPTION]... [-- <lustre configure options>]
Options:
--build
same as --build-kernel --build-lustre --unpack-kernel
--build-lustre
configure and compile lustre. Requires that --build-kernel was
already run.
--build-kernel
configure and compile a kernel. Implies --depend-kernel.
Requires that --unpack-kernel was already run.
--depend-kernel)
Prepares a kernel tree for building (similar to make mrproper
oldconfig dep). Requires that --unpack-kernel was already run.
--destdir=DESTDIR
Root directory to install into (like DESTDIR with auto*).
--extraversion=EXTRAVERSION
Overrides the target kernel\'s EXTRAVERSION text.
-h, --help
Display this message.
--install
same as --install-kernel --install-lustre
--install-lustre
run make install in the Lustre tree.
--install-kernel
install the kernel image and modules.
-j jobs
This works just like the -j option to make, and is passed to make
when building.
--kerneldir=KERNELDIR
Directory containing linux source tarballs.
--target=TARGET
Name of the configuration to use. The available targets are
listed below.
--target-arch=ARCH
Specifies an architecture to use when choosing a kernel config
file. Default is i386.
--target-config=CONFIG
Specifies a special option (such as smp, bigsmp, bigmem, or BOOT)
to use when choosing a kernel config file. This also modifies the
kernel version and modules directory.
--unpack-kernel
Untars and patches the kernel source.
The order that commands (--build-lustre, --unpack-kernel) are
specified on the command line is ignored; ${0##*/} will always
execute them in the correct order (unpack, then build, then install
etc.).
