These images are selected as being more "lucky", where the luck factor
comprises of mkimage-profiles development resulting in improvements for
the particular image and the general state of all the related components
in Sisyphus (which is a live development repository so can have its own
highs and lows).

Generally the images from tested/ directory are preferred
but sometimes you might want to use one of these:
