I made a patch to migrate the MediaWiki-Vagrant clone used by role::labs::vagrant from /mnt/vagrant to /srv/vagrant [0] that was merged into operations/puppet.git today. Unfortunately, this patch has a bug that leads to non-deterministic behavior. The outcome in the crap-bryan-why-did-you-break-that case is that the contents of the old /mnt/vagrant directory were copied to /srv/vagrant *before* the new disk partition was mounted. This happened to at least 2 labs-vagrant hosts that I know of. When it does happen, all is not lost!
