Do not use the embedded Vagrant ruby by default.
Rubber 2.5.2.
Allow the Vagrant plugin to interact with the local ruby installation when RVM is used.
Make sure we note the vagrant provider was used in the instance file.
Ensure that 'update-notifier-common' is installed before doing a dist-upgrade, otherwise we won't know if the machine requires a reboot.
Annotate hosts with provider value so we can filter tasks by provider more easily.
Upgraded to the latest version of ruby-build and use the latest 1.9.3 release by default.
Re-install VirtualBox additions after bootstrapping a Vagrant instance so the additions match the kernel version.
Updated Digitial Ocean default zone info and image_id
Fixed legibility.
Fixed weird comment.
Ensure the SSH public key is installed for the user account if one is set.
