Earlier this month published ‘reposervice’ to GitHub. Reposervice is a “self-contained” Islandora installation source tree that is intended to smooth the LYRASIS deployment of repository services between development servers, a staging server and production servers. It is a bit of a work-in-progress at the moment, but others might find it useful as well.
(By the way, if you had looked at Reposervice prior to June 18th, you may have noticed a missing critical element — the Drupal submodule. Not because you couldn’t add Drupal yourself but because the Reposervice clone has relative soft symlinks to the Islandora modules positioned in the top level Reposervice directory.)
