Major Description
The InitialContent installs a bunch of content nodes before the CommitHooks are enabled.
This hurts the query indexes as they don't get notified about the initial content and cannot index/process it.
I'm mostly referring to the Auth stuff that relies on a combo of initial content & queries.
Luckily when using the PropertyIndex it does fallback to full repository traversal, which works (albeit slowly). Unfortunately I can't say the same for the lucene index).
A bit of context here [0].
