To update on this, it was just pointed out to me by matt farrallee
that the auto fix of permissions is for a failsafe
in case of a race condition, and not meant to mend bad permissions in all cases:
Something to keep in mind - if you see the "fixing staging permissions" error message alot
Then there might be a more systemic problem in your fs... At least, that was the case for us.
