 164
 165   --kerneltree=KERNELTREE
 166     Directory containing dirs with Linux source tarballs referenced by target
 167     files. Dir names in format kernel version ('2.6.9', etc.)
 168
 169   --linux=LINUX
 170     Directory of Linux kernel sources.  When this option is used, only

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