OK, I kinda see what you're saying now - the way the images work, the
size of the compressed image we ship is more or less irrelevant.

I believe in the case where the bits in the image are too large for the
filesystems, compose fails, right? So there is basically no purpose to
running size checks on those images. Sorry I didn't quite grok that
earlier (in the bug report).

If that's the case, we can write a note into the size check test case
(and the criteria, if it looks necessary) that size checks are not
necessary for the disk image media.
