131     tree.
132
133   --extraversion=EXTRAVERSION

157
158   --patchless
159     Build lustre client only
160
161   --distro=DISTRO
162     Which distro using. Autodetect by default
163
164   --kerneltree=KERNELTREE
165     Directory containing dirs with Linux source tarballs referenced by target
166     files. Dir names in format kernel version ('2.6.9', etc.)
167
168   --linux=LINUX
169     Directory of Linux kernel sources.  When this option is used, only
170     Lustre modules and userspace are built.
171
172   --lustre=LUSTRE
173     Path to an existing lustre source tarball to use instead of
174     pulling from CVS.

177     Do not try to download a kernel from downloads.lustre.org
178
179   --nosrc

181     tarball.
182
183   --ldiskfs
184     Do ldiskfs RPM. Now true by default
185

198     more or less in DIR/<target>-<arch>, and the tarball will be
199     placed in DIR.
200
201   --tag=TAG
202     A CVS branch/tag name to build from when pulling from CVS.

209     A (space delimited) list of architectures to build.  By default,
210     all of the archs supported by the TARGET will be built, in
211     addition to a .src.rpm.  This option can limit those, for machines
212     that can only build certain archs or if you only want a certain
213     arch built (for testing, or a one-off kernel).
214
215     Also note that by using a non-"base" arch (eg, i386) only kernels
216     will be built - there will be no lustre-lite-utils package.
217
218   --disable-datestamp
219     Prevents the datestamp flag (-D) from being passed to cvs for 
220     checkouts. This is a workaround for a problem encountered when 
221     using lbuild with tinderbox.
