I think you already explained that you're removing the UUID to make the
filesystem creation reproducible (i.e avoid having random bits in the
filesystem image). Even though I'm not it's entirely feasible (some
binaries inside the filesystem may contain build dates and things like
that), I think it's an interesting goal. So my only suggestion here
would be to extend a bit your comment, to explain *why* you do not want
this UUID.

Maybe we could set the volume name to 'buildroot' ? I.e:

	tune2fs -L buildroot "${IMG}"
