all the paths in a recipe. So I just copy others and try things that
eventually work.

The basic rule is that for a file: uri in a SRC_URI field, relative to the .bb it searches $PN-PV, $PN, then files/.

Obviously there are complications with extending that search path, and .bbappends extending the search path, but that's the underlying principle.

The practical result of this is that you can split general, per-package, and per-version files, which is useful when for example you need different patches per version of a package, but all versions can share an initscript.
