Added struct to be passed to the Process function to render the vagrant ...

The second link is to the correct id.

"Explicivity" is not a word.

This changes the SaltStack bootstrap URL to use the HTTPS link from the commercial site.  Alternatives are the HTTPS link to the raw file on GitHub, but this, whilst more transparent, might break down the line.

Otherwise, the error message will be displayed in GUI:
"Unable to connect CD/DVD 0"
