Autodetect by default --kerneldir=KERNELDIR Directory containing Linux source tarballs referenced by target files. --kerneltree=KERNELTREE Directory containing dirs with Linux source tarballs referenced by target files. Dir names in format kernel version ('2.6.9', etc.) --linux=LINUX --with-linux=LINUX Directory of Linux kernel sources. When this option is used, only Lustre modules and userspace are built. --lustre=LUSTRE Path to an existing lustre source tarball to use instead of pulling from CVS. --nodownload Do not try to download a kernel from downloads.lustre.org --nosrc Do not build a .src.rpm, a full kernel patch, or a patched kernel tarball. --ldiskfs Do ldiskfs RPM. Now true by default --publish Unused. --release Specifies that the files generated do not include timestamps, and that this is an official release. --src Build a .src.rpm, a full kernel patch, and a patched kernel tarball. --stage=DIR Directory used to stage packages for release. RPMs will be placed more or less in DIR/-, and the tarball will be placed in DIR. --tag=TAG A CVS branch/tag name to build from when pulling from CVS. --target=TARGET The name of the target to build. The available targets are listed below. --target-archs=TARGET_ARCHS A (space delimited) list of architectures to build. By default, all of the archs supported by the TARGET will be built, in addition to a .src.rpm. This option can limit those, for machines that can only build certain archs or if you only want a certain arch built (for testing, or a one-off kernel). Also note that by using a non-"base" arch (eg, i386) only kernels will be built - there will be no lustre-lite-utils package. --disable-datestamp Prevents the datestamp flag (-D) from being passed to cvs for checkouts. This is a workaround for a problem encountered when using lbuild with tinderbox. --xen Builds a Xen domX kernel.
