This test seems a little bit fragile.  How about something like:

NEWEST_PACKAGE=`ls -t ${DEPLOY_DIR_IPK}/$ipk_path/*.ipk | head -n 1`
if [ -n "$NEWEST_PACKAGE" ] && [ "$NEWEST_PACKAGE" -nt
"${DEPLOY_DIR_IPK}/$ipk_path/Packages" ]; then
 ...

instead?  Or, perhaps even better, teach ipkg-make-index to do this
checking for itself and just return immediately if there's no work for
it to do.
