 153     files.
 154
 155   --kerneltree=KERNELTREE
 156     Directory containing dirs with Linux source tarballs referenced by target
 157     files. Dir names in format kernel version ('2.6.9', etc.)
 158
 159   --linux=LINUX --with-linux=LINUX
 160     Directory of Linux kernel sources.  When this option is used, only

 203     that can only build certain archs or if you only want a certain
 204     arch built (for testing, or a one-off kernel).
 205
 206     Also note that by using a non-"base" arch (eg, i386) only kernels
 207     will be built - there will be no lustre-lite-utils package.
 208
 209   --disable-datestamp
