I’ve never done this, but I believe server network cards can be configured for PXE automatically so

Bios -> network card -> PXE over network

So the storage is in the bios config, and then I guess the network card has its own kind of bios?

    So there is still one single damning piece of information stored in the servers after all - the IP address to fetch the PXE boot image from. But hey, if Mullvad finds a way to strip even that out of the servers, that'd be great

    Why is it damning?

    Because by knowing which IP is the boot image stored from, law enforcement can locate the source of the unencrypted image, thus making the scheme lose its privacy. The only way to bypass the issue is by manually configuring the IP after every reboot and keeping it a secret.

    Why does being able to access the unencrypted image pose such a problem?

    Because by doing so, law enforcement can manipulate the image from the source by:

    • Intercepting the payload and modifying the operative system to send data to law enforcement
    • Pose as the origin of the original payload, and send the tainted operative system to other devices when they reboot

    Unless, of course, the BIOS stores the checksum of the untainted image. (Which adds its own can of worms, because that would make legitimate image upgrades require writing the new proper checksum on each server)
