Do some tradition sync calls at the end. This comes up
because I see that packer has an attribute to set the
shutdown in some builders and the problem I'm having
with digitalocean might be similar.  I.e. nothing seems
to change in the snapshot inspite of it happening in
the transcript.
Convert install-emacs24 so it runs as root, rather than the user.
Hopefully, testing is running now.
The vmware builder is now two different kinds, so use vmware-iso.
Add the required shutdown_command.  Optomistically add back
install_emacs24, which might work now that we shutdown more
cleanly.
Finish the switch to vmware-iso.
