[Container-tools] Modifying VARIANT in /etc/os-release has side effects

[Dusty Mabe]

The vagrant-service-manager plugin is modifying the "flavor" guest capability [1].

This has side effects on code (example at [2]) that assumes it is going to get back
the that is returned from the actual flavor cap in vagrant core code [3].

This is why hardy had such a hard time getting sshfs installed on his
machine earlier today. The vagrant-sshfs plugin wasn't able to
properly detect things and it didn't install sshfs for him.

Opening up an issue on the plugin at [4]
