Being all about choice I have to agree that as long as we have both bin
and normal kernels there is nothing wrong with that. However, dear god,
with how many kernels we have won't this get really expensive really
fast? Even just signing gentoo-sources and hardened-sources would cost
a fortune considering both change weekly if not daily. So that puts us
to signing just stable releases and damn users who want secure boot and
a recent kernel or need a custom patch? This all seems like a huge step
in the wrong direction to me, at the very least the amount of effort for
this is near insurmountable in my eyes.
