I think the idea here is good, the implementation is suboptimal though.
The reason being it introduces more variables which do things outside a
clear namespace (ARTIFACTS_ONLY).

I'd really like to see this code trigger off an entry in IMAGE_FSTYPES
like IMAGE_FSTYPES = "live-artifacts-only" or some other such keyword.
The ultimate idea is we'd get rid of all these class specific variables
and you'd just set IMAGE_FSTYPES according to what you want.

The depends on COMPRESSISO also looks like a cut and paste which I'm
not sure could trigger in this codepath?

Cheers,

Richard
