So what, the final initramfs would contain a statically linked executable to run as init that would do the secrets thing and then delegate to the main init? The idea that the rest of the initramfs is outside the trust boundary and potentially hostile makes me queasy - I guess the boundary has to sit somewhere, but a single file that has trusted and untrusted parts concatenated together is going to be surprising. But a way to get the properties we need out of the parts we already have is very cool, even if it ends up slightly hacky.
