I think disk util reapir and commandline repair does the same.

I read about this Chameleon /Extensions problem here and some solution by an added subfolder.
But i dont understand it really, because i dont know how Chameleon exact works (whats loaded from where when )

Scroll down to part of Chameleon install for that ??? about added
sudo mkdir /Extra/AdditionalExtensions folder (for the kexts)
