The bd808-vagrant.wikimania-support.eqiad.wmflabs Labs instance hosts http://wikimania-vagrant.wmflabs.org which is a build and distribution server for creating MediaWiki-Vagrant ISO images suitable for use on USB sticks for install parties and hackathons. This instance used a self-hosted puppetmaster (not sure why now) and ended up in a very broken state following a Labs LDAP server migration.
A new mediawiki-vagrant labs project has been created to host a new build server. Create a instance, set it up with the MediaWiki-Vagrant labs role and make it run support/packager/build.sh to generate a daily ISO image.
