  I think this very much falls into the category of featuritis.

  In many situations, you'll want a script around 'make' to automate 
things beyond what buildroot does. As long as this script only does 
things _before_ and _after_ the 'make' invocation, there is no need for a 
change in buildroot infrastructure. And these top-level scripts are so 
different from project to project that it doesn't make sense to include 
them in buildroot either.

  For example, here's a script that will automatically take a defconfig 
and copy the images to the target:

#! /bin/sh
# Wrapper around make

# We allow running from a foreign directory
topdir="$(dirname $0)"
[ "$topdir" = . ] && output="output/" || outdir="O=$PWD"
MAKE="make -C $topdir $outdir"

if [ ! -e .config ]; then
   $MAKE project_defconfig
fi

echo $MAKE "$@"
$MAKE "$@" || exit $?

imgfiles="${output}images/bzImage ${output}images/rootfs.cpio.bz2"

# Terminate if image files were not generated
for f in $imgfiles; do
    [ -r "$f" ] || exit 1
done

if [ "$TARGET_IP" ]; then
   scp $imgfiles root@$TARGET_IP:/mnt/boot
   ssh root@$TARGET_IP /sbin/reboot
fi


  There is really no need to change buildroot to support this kind of thing.

  Arnout
