Currently, do_rootfs has a dependency on all the do_package output being present due to its usage of the pkgdata directories. This means that if you run: bitbake xxxx-image -c rootfs you end up having to fetch and unpack all the do_package data which is usually large and inefficient. It also means rm_work has to leave all the do_package data lying around so rootfs works. This patch splits the actual creation of the pkgdata directory off into a separate task, "packagedata" which happens immediately after do_package. We can then remap the dependencies so this task is depended upon, not do_package. Sstate can then be programmed not to require do_package at the appropriate times. Whilst this patch doesn't do so, it opens the possibility of rm_work wiping out the do_package output from WORKDIR as long as it also removed the do_package stamp (both normal and setscene variants) and allowing more space savings with rm_work which has been regularly requested.
