So here's what I'd like to try:
- write a new populate_build_replica task that writes a few things
under ${WORKDIR}/replica
-- setup-layers json and script
(another option is to copy the layer trees themselves like esdk does,
which is left for maybe later. Completely offline replication is not
an initial goal, and it's good to get to a minimally viable
implementation asap.)
-- meta-build-config layer with the local.conf/bblayer.conf template.
-- sstate cache needed to fulfil the bitbake target that the task is
for (this would reuse code from esdk that does the same as much as
possible)
All of this is then packaged into a self-extracting shell archive that:
- unpacks itself
- fetches layers using the json/script from the unpacked tree
- sets up a build directory using the template from meta-build-config
in the unpacked tree
- tweaks site.conf to point to the prepackaged sstate
And voila! (in theory) This should be the same build as the one that
was produced elsewhere.
