We can never get 100%, but that's no excuse to at least try to do
better. It's why I believe the reproducible builds project in Debian
[1] is a great start: rather than blindly trust even direct PGP
signatures on blessed binaries, we can also have entities
independently build in multiple instances to at least vouch that, for
a given set of sources, with a given toolchain, this exact sequence of
bits and bytes should be generated for a given binary.
A sort of poor-man's proxy for verification by way of consensus.
