Okay, I see.  Does it support variable interpolation?  If the
permissions are going to be specified out-of-band then I think at a
minimum there needs to be a way to refer symbolically to things like
${prefix} rather than hardcoding their values.

Also, from what you wrote above about device_table-minimal, it sounds as
though this file is a global manifest rather than being per-recipe.  Is
that right?  If so, it sounds like this is going to be a frequent source
of merge headaches in much the same way as the old checksums.ini was.
