[yocto] externalsrc + sstate why is not compatible?

[Koehler, Yannick]

Ok, will try that.  If that works, I may see if I can alter the file fetcher to use symlinks, not sure if sstate subsystem will like that or not.

If we do so, and someone change the file in /src/somedir will yocto redo the fetch/unpack pattern to recopy over the original content by itself?

If you have:

	SRC_URI := "file://some-dir/"

and your tree looks somewhat like this:

	.git
	poky
	src/some-dir

and you set things up so that bitbake will look in src/ (set FILESPATH), then it will copy "some-dir" to $WORKDIR/some-dir, and you can point S there.

This satisfies your requirement as I understand it (single repo, all the source code is there, including poky).

The huge downside of this is that some-dir is copied and this confuses people.

I know the bitbake version in 2.4 has some differences that might help here, but I haven't had the chance to investigate further.
