Support for providing box type at initialization, i.e. vagrant init debian_lenny

[KieranP]

The ability to provide the box type at initialization would save a trip into an editor and speed up the process.

vagrant init debian_lenny

vagrant init now takes an optional parameter to specify the default box [closed by 4229b65]

Kieran,

Implemented: http://github.com/mitchellh/vagrant/commit/4229b65a8179ff0dca4ec4f15411f8439f95c653

Thanks. It was based heavily off of your fork, but abstracted a bit more as I intend to use the renderer for other parts of the system.
