Hmm, you're right. The word bootstrap implies that we're starting from
nothing, which is exactly what we're *not* doing (starting from nothing
is the easy "clean install" case). By the same token, FROM NOTHING
isn't the right phrase either. An accurate description would be
something like FROM UNPACKAGED OBJECTS, but I'm not seriously proposing
that ...
Other ideas anyone?
