That seems like the wrong approach. The kernel can actually distingush
many of these cases, so it could just tell the user about them directly.

This the kernel knows so it could just say. In fact it's already

This is knows also.

No idea what that should be.

I think you're refering to shared libraries here. This is actually not correct,
because if dynamic linking for init fails this will not result in this error message.

This it also knows.

So please just fix the output.
