It includes skas as well, but remember you must do mrproper between building UML and host kernel or use O= with two different output directories (as I do): mkdir ../BUILD OUT=../BUILD/um-linux-2.6.16-build mkdir $OUT make ARCH=um SUBARCH=i386 O=$OUT menuconfig make ARCH=um SUBARCH=i386 O=$OUT OUT_HOST=../BUILD/64-linux-2.6.16-build mkdir $OUT_HOST make O=$OUT_HOST menuconfig make O=$OUT_HOST Bye -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
