with additional IRC chat about hrw's umbaumba-wonders :P moved to
recipes/images/shr-image.inc in faster version (which moves only /boot)

# We don't want /boot directory in jffs2/ubi/ubifs images
IMAGE_CMD_jffs2 = "
mv ${IMAGE_ROOTFS}/boot ${IMAGE_ROOTFS}-boot 
&& mkfs.jffs2 ....
&& mv ${IMAGE_ROOTFS}-boot ${IMAGE_ROOTFS}/boot"

Any better idea?
