Thanks. That'll get me over this hump.

While I was out at my daily workout, I was thinking about this. Is it
possible to mimic the directory structure in the metadata, in this case
pushing the file down a level, and then specifying that subdirectory name
in front of the filename in the SRC_URI, instead of as a "subdir" option
after it? Or must file:// always be followed by a simple filename?

I'd experiment with it, but I have a reallly slooow build system which
takes about fifteen minutes just to do the do_rootfs.
