You are correct, but this is something that has bothered me.

At the moment we handle this by embedding the definition for one file
into the one that uses it. This is on the theory that there is no need
to actually write the embedded file, since it is a temporary file. In
fact binman does generate temporary files though.

Is that good enough? If not I'd like to understand the need better,
before we make any changes.
