  95
  96   -d CVSROOT
  97     Specifies the CVS Root to use when pulling files from CVS.  The
  98     environment variable \$CVSROOT is used if this option is not
  99     present.
 100
 101   --external-patches=EXTERNAL_PATCHES
 102     Directory similar to lustre/lustre/kernel_patches/ that lbuild should
 103     look for seres and config files in before looking in the lustre
 104     tree.
 105
 106   --extraversion=EXTRAVERSION
 107     Text to use for the rpm release and kernel extraversion.
 108
 109   --kerneldir=KERNELDIR
 110     Directory containing Linux source tarballs referenced by target
 111     files.
 112
 113   --linux=LINUX
 114     Directory of Linux kernel sources.  When this option is used, only
 115     Lustre modules and userspace are built.
 116
 117   --lustre=LUSTRE
 118     Path to an existing lustre source tarball to use instead of
 119     pulling from CVS.
 120
 121   --nodownload
 122     Do not try to download a kernel from ftp.lustre.org
 123
 124   --nosrc
 125     Do not build a .src.rpm, a full kernel patch, or a patched kernel
 126     tarball.
 127
 128   --publish
 129     Unused.
 130
 131   --release
 132     Specifies that the files generated do not include timestamps, and
 133     that this is an official release.
 134
 135   --src
 136     Build a .src.rpm, a full kernel patch, and a patched kernel tarball.
 137
 138   --stage=DIR
 139     Directory used to stage packages for release.  RPMs will be placed
 140     more or less in DIR/<target>-<arch>, and the tarball will be
 141     placed in DIR.
 142
 143   --tag=TAG
 144     A CVS branch/tag name to build from when pulling from CVS.
 145
 146   --target=TARGET
 147     The name of the target to build.  The available targets are listed
 148     below.
 149
 150   --target-archs=TARGET_ARCHS
 151     A (space delimited) list of architectures to build.  By default,
 152     all of the archs supported by the TARGET will be built, in
 153     addition to a .src.rpm.  This option can limit those, for machines
 154     that can only build certain archs or if you only want a certain
 155     arch built (for testing, or a one-off kernel).
 156
 157     Also note that by using a non-"base" arch (eg, i386) only kernels
 158     will be built - there will be no lustre-lite-utils package.
 159
 160   --disable-datestamp
 161     Prevents the datestamp flag (-D) from being passed to cvs for
 162     checkouts. This is a workaround for a problem encountered when
 163     using lbuild with tinderbox.
