I figured out just a few minutes ago that the changes I had made were
undone by the mediawiki::packages class in puppet shortly after I made
them this morning. I have updated my giant-puppet-hack-patch™ [1] to
have puppet ensure that the changes I'd made manually are made by
puppet now [2]. If this change needs to be un-done in a hurry:
* Edit /var/lib/git/operations/puppet//modules/mediawiki/manifests/packages.pp
on deployment-salt.
** Set the target for File['/usr/local/apache/common-local'] to
'/data/project/apache/common-local'.
* Force a puppet run on the
deployment-{apache0[12],videoscaler01,jobrunner01} hosts.
