@Germano0, it's an internal ticket tracking system.
Generally you don't need an access to it

@Germano0 the ticket system used to be public, but there were some security concerns with JIRA in the past and it was restricted. Since the BOINC-Drupal project is not under active development from many people in the BOINC community, there would be reluctance to opening that ticket system back up to the world; but if you want an account to see the discussion / context, I can set that up for you, no problem.

As for the PR, thanks for the revised approach, Shawn. I think this should help to ensure everything works as expected when a Drupal site is initialized.
