Just got my Intel Mac to NetBoot from a NetRestore volume. Just like the boot selector you see when starting up with the Option key held down has been visually updated, so has the flashing globe icon you see when starting up with the N key held down (to initiate a NetBoot).
I imagine the FireWire icon you see when starting up in Target Disk Mode has changed as well; I’ll look at that after the disk restore is complete.
(EDIT) Yup. That icon is different as well – large and white with a gray background that matches the desktop.
