I just hope that if and when the full installer is released for beta 8, that the SharedSupport fiasco will be resolved.
For those not aware of this, in beta 7 a major part of the full installer was missing and there were various ways of fixing it - some more successful than others - and until you fixed it you couldn't make a bootable usb.
For beta 7 you downloaded an 11.7GB full installer only to end up with a 34.8MB installer app - only to then have to re-download the 11.7GB SharedSupport to fix it.
I do hope that apple won't say something stupid like it's a new feature, not a bug - because if it is a feature, it is a REALLY STUPID FEATURE!
