After upgrading to 7.3.0 and going through all the steps to set up the internal boot, there seems to be a problem with the file transfer process. After going through the Onboarding Wizard everything completes fine (although the copy stage goes so quick, it's likely failing), then when the system reboots not using the usb drive it quickly errors at "bzmodules checksum error."

I've attached the diagnostics and I believe it's the copy step of the Onboarding Wizard that's breaking somehow.

The copy is not logged, but it just uses rsync, look at the monitor output the next time you try it; it shows there, it's done just before the reboot.
