Just because there is a symlink doesn't mean boot2 has
to follow it.

I haven't looked at the boot2 code, but I presume
there's the equivalent of "chdir boot" in there.
What if you just ignored failure (if there's no
"boot" entry or "boot" isn't a dir, assume the
boot files are in the root of the FS).

Wouldn't that work just as well and require less space?
