So is there a "current" VMMaker version that includes these? (I'm asking
since when Josh sent the message lately you replied by pointing to a
webpage with a few bits of loose code on there ;-)

No, I don't know. The main thing is that I need a way of computing the
checksum for the actual binary (not just a shell script which invoked
the the binary somehow) and I would expect that getSystemAttribute: 0
gives us the shell script, no?

An alternative would be to require a primitive that gives us a build
UUID but I'm trying to avoid that.
