I don't understand why anyone would use passwordless disk encryption. It just seems inherently vulnerable, especially with the threat model of physical compromise.

Entering a password on boot isn't even that much work

You want to install and operate a device at a remote site with restricted (or no) VPN access and where you don't trust the local staff?

A remote KVM, i.e TinyPilot will help avoid dealing with lack of trust in local staff. Additionally connection to the KVM can be done over LTE/Cellular if you don't trust the local connection too.

How does this make sense?

Any change the untrusted local staff could make to the server, they could also make to the KVM machine (e.g. turn it into a keylogger).

Now you have the same problem but with a smaller computer.

You cannot turn untrusted systems into trusted systems by adding more untrusted systems.
