It actually runs git (with hooks disabled) to generate the diff. It happens on the host when using copy mode, and inside the sandbox when using overlay mode.

The above example doesn't specify workdir mounting mode, so it would be copy, not overlay.

If it runs inside the sandbox and the guest is compromised, can't the guest just lie?

[kstenerud]

Absolutely. That's why overlay is not the default.

[creata]

That's... uh, an interesting approach to security.

[kstenerud]

What is? Defaulting to the most secure method?
