Concerning trust, the classic way it has been solved before (by seti…)
is to farm the same build to several independant nodes, cheksum results
and make sure they all agree

Of course that supposes builds are strictly reproductible (centos folks
would love this) and that makes the system a lot less efficient. But
then, trust has a price too
