Building boxes results in files with unhelpful names

[davidjb]

I'm using the latest version of Bento from git and finding that if I build a box like so, following the instructions:

packer build -only=virtualbox-iso -var 'mirror=...' centos-7.1-x86_64.json

the result is that the box is named builds/__unset_box_basename__.virtualbox.box. This isn't very helpful, especially when I was building two boxes from different OSes at the same time.

I note that the string __unset_box_basename__ is hard-coded into most, but not all, provided JSON files in Bento and that the comment at #430 (comment) mentions how to configure the box basename.

If that comment is the prescribed the way to avoid the above problem, then may I suggest documenting this process in the README? Otherwise, can a more useful name be set in each JSON file?

Yes to both questions - PR #434 is addressing the first part and I'm planning on reverting to friendlier and more generally useful names.

That was initially something that was done to serve our needs for the bin/bento tool but has proven a bit more confusing than helpful.
