True, but I'm still hoping there is a solution that does not require
changes to the release tree. I would have to re-apply those changes
whenever I update one of the releases (including the often changing sid)
and make sure there are no compatibility issues with the rest of the
boot image.

Why is the working directory specified by CONFIG not used to retrieve
ldlinux.c32? Couldn't that be considered an error?

I tried using PATH but found that it will add to the list of directories
searched. Is there any way to specify a search path specific to the
scope of each LABEL in pxelinux.cfg/default?
