Hmm. Can we keep “image” persistent by default, and make ‘vm’ volatile
by default? That way, ‘--volatile’ would only make sense for ‘image’,
and ‘--persistent’ would only make sense for ‘vm’. (So we’d be adding
just one option: ‘--persistent’.)
WDYT?

Leo had a point on the size of those files, and the fact that if they’re
in ~/.cache they’re not going to be removed automatically, which could
lead to user disks filling up.
So after all, it might be best to keep those images in ${TMPDIR:-/tmp}.
I would still ensure they have a name like “guix-image-$USER-XXX”, where
XXX is the store file basename.
Thoughts?
Apologies for the hesitations!
Ludo’.
