Which log source distinguishes driver signing failures from missing packages in Windows 8 deployment?

Deployment Log Ambiguity

During a Windows 8 deployment, the setupact.log within the Panther directory records installation phase errors. However, generic failure messages such as \"Failed to install driver package\" can occur regardless of whether the root cause is a missing dependency or a signature verification failure.

While error codes like 0x80070002 typically indicate a missing file and 0x800B0100 signals a driver signing problem, the Deployment-Services operational log in Event Viewer often mirrors the setupact entries while omitting verbose signature details unless the log level is manually adjusted.

Diagnostic Uncertainty

It remains unclear whether increasing log verbosity via the <Debug>true&true element in the answer file is sufficient to capture the specific threshold for driver signing warnings, or if manual cross-referencing with the Code Integrity operational log is mandatory to distinguish these from package omissions.

• Does the Deployment-Services log provide distinct event IDs for signature failures when set to verbose?
• Which specific log should be cross-referenced to definitively separate a 0x800B0100 signature error from a package error?
