 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

 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
