[yocto] Creating a new recipe based on another recipe

[Daniel.]

I think you're searching for .bbappend don't?

http://www.yoctoproject.org/docs/current/dev-manual/dev-manual.html#using-bbappend-files

Or, maybe, put all the common things in a .inc file, create the recipes,
include the files in recipes. There is also a lot of examples of this:
