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

 214     that can only build certain archs or if you only want a certain
 215     arch built (for testing, or a one-off kernel).
 216
 217     Also note that by using a non-"base" arch (eg, i386) only kernels
 218     will be built - there will be no lustre-lite-utils package.
 219
 220   --disable-datestamp
 221     Prevents the datestamp flag (-D) from being passed to cvs for
