A couple followup points: - copy_buildsystem() in populate_sdk_ext class is overly long at 400 lines and does many different barely related things, writing local.conf for esdk one of them: https://git.yoctoproject.org/poky/tree/meta/classes-recipe/populate_sdk_ext.bbclass#n189 The first step would be to structure it into separate functions each doing one thing and hopefully fitting on a single screen. Then these functions can be hand-picked into a task designed to provide esdk things in a yocto build context, and the code would simply be more readable, as right now I can barely understand all the various things that function does, and the spaghetti of local variables etc. - the tool that would set up the esdk environment in a plain yocto build could be a shell script in scripts/oe-init-esdk-env perhaps, similar to oe-init-build-env. No need to make it a devtool plugin; it could use python helpers to program the more tricky bits such as PATH manipulations etc. So one would first initialize the yocto environment, then transition to an esdk environment from that (there would be no way to go back, as one can simply start a new session).
