I guess not many would use the remote attestation capability offered by DIGLIM (sealing a TPM key to the software running in the machine). The two scenarios in which that could be used are: - web servers or other kind of servers where you, as client, would like the guarantee that your data is processed only if the software running in the server is not compromised - closed networks where you, as network administrator, would like the guarantee that your clients can access those networks only if their software is not compromised Probably, the secure boot functionality at application level is much more appealing, and less invasive. It should have almost zero impact if the users use their system for web browsing or writing. Although it is unlikely to happen, this feature prevents arbitrary execution of software, even by root. The trust anchor will be the kernel, and one would not have to rely on the correct execution of the package manager (and on its verification of the package signature). If the users often make changes on their system, but confined to their environment, DIGLIM could still be helpful, as the damage of running arbitrary software will be limited to the users environment (no arbitrary software execution as root). If the users often make changes on their system, with high privileges, I agree that DIGLIM would simply cause too much overhead for the configuration (every time the users make a change, they have to whitelist their software).
