I've just verified on my machine that WITHOUT_MODULES will only strip out top level module directories. You cannot pick and choose subdirectories like the handbook suggests. I'm guessing someone cut & paste the MODULES_OVERRIDE line to add the WITHOUT_MODULES entry. Selecting subdirectories works in the MODULES_OVERRIDE case, though, because you can add a subdirectory even if the original list you are replacing only contains the top level module directories. Also, the current implementation of WITHOUT_MODULES does not support being set in your kernel config using makeoptions. This patch fixes that for me: Index: sys/conf/kern.pre.mk =================================================================== --- sys/conf/kern.pre.mk (revision 254) +++ sys/conf/kern.pre.mk (working copy) @@ -163,6 +163,9 @@ .if defined(MODULES_OVERRIDE) MKMODULESENV+= MODULES_OVERRIDE="${MODULES_OVERRIDE}" .endif +.if defined(WITHOUT_MODULES) +MKMODULESENV+= WITHOUT_MODULES="${WITHOUT_MODULES}" +.endif .if defined(DEBUG) MKMODULESENV+= DEBUG_FLAGS="${DEBUG}" .endif Hope that helps. - Benhelp
