What I would like to try is have oe-setup-layers first clone/checkout the layer repositories (according to what is in the supplied json), then walk the resulting directories looking for conf/layer.conf, e.g. determine what actual layers are in the checkout and where they are. Then this list would be written out to a file in the top level directory containing the layer repos for further usage by other tools. E.g.: /path/to/setup-layers --destdir path/to/checkout/ would write a path/to/checkout/oe-layers.txt (final filename TBD) containing layer paths relative to the file itself, e.g. (final format also TBD) meta-intel meta-arm meta-openembedded/meta-oe meta-openembedded/meta-networking and the location of oe-setup-build into a runnable shell script path/to/checkout/setup-build.sh: #!/bin/sh poky/scripts/oe-setup-build --layers-list ./oe-layers.txt $* This leaves bblayers.conf(.sample) unchanged and exactly as it was - a template/build item consumed by bitbake only and used to list layers active in a specific build.
