Hey, thanks for this, very helpful.
Would you mind to explain me why RVM and NODE are being installed with "su - vagrant -c" ?

@vasconcelloslf I think because that command can safely be run as "vagrant" user. The -c is simple to run a command as the user indicated in the su.
@johanneswuerbach, thanks a lot for sharing this snippet!

Almost exactly what I needed, thanks!
