Comment on The creator of systemd wants your entire system validated by SecureBoot
nyan@lemmy.cafe 21 hours agoThe chain of trust starts with the owner of the hardware, not some random corporation that happens to make an OS. The owner can, if they wish, outsource the root of the chain of trust to a corporation, but that should be an active decision on their part, not something that happens just because the hardware was shipped with some random OS preloaded.

The thing is in such a case secureboot doesn’t help and is unnecessary. Secureboot only does anything for the concept of “trusted suppliers”.
If the system has available signing keys for itself, well, hypothetical malware could sign itself using those same keys The OS security mechanisms are the only things protecting that, and in which case the signature validation is redundant.
You can have trusted boot, e.g. LUKS volume sealed to TPM PCRs, but secureboot just doesnt make sense as a mechanism for a user to only trust themselves.

Thing is, that means you don’t really own the hardware that you buy, because a corporation is dictating what you can do with it even though it doesn’t belong to them. Most of us consider that unacceptable.
