[yocto] Adding SCM'ed files to image

[Lars Larsen]

Hello world

I've been struggling a bit, but I'm sure there must be a generic 
solution to my problem (as a bbclass perhaps ??)

I'm building a bootable  image (NOT a distribution) for our product.

But I need a simple recipe to copy some files
I have a bunch of files (scripts, configuration files etc)  these files 
are under git control, I want the directory  structure in the 
repository, populated on to the image

so in my git I have something that could look  like this
.
├── bin
├── etc
│   └── file_in-etc
└── usr

I want it overlayed on the target image,

It proved surprisingly difficult when the files are not a precanned part 
of the recipe (in a files directory). the recipe doesn't know the dirs & 
files in advance.
I managed to get the structure  checked out in WORKDIR/git but getting 
from  her to  the image still troubles me


I'm sure somebody else had the same issues, but I can t find an elegant 
solution

any pointers will be highly appreciated
