The reason I mentioned dynamic allocation is that you still need to do
dynamic allocation if you're using a blob from an external source.  If
you don't end up with pointers *into* the blob, though, then you don't
need to do the relocation until some time before you jettison the init
section.

However, I don't have a strong opinion about which way it's done.
