[Cuis-dev] [TIP] Executable images on Linux

[Luciano Notarfrancesco]

Cool, I didn’t know you could do this! Which reminds me, sometimes I wonder
if we really need the sources and changes files outside the image, it’s
just 8MB… perhaps it would be nicer for images to be self-contained
(although the changes file still makes sense for recovery in case the image
breaks).
