Don't remove rpmlib when INC_RPM_IMAGE_GEN=1, otherwise the

What happens when I do a build, enable INC_RPM_IMAGE_GEN and do
another build?
The intention is that only the packages that have been
changed/upgraded will be installed. Instead of the whole image
being generated from scratch each time.
That's what INC_RPM_IMAGE_GEN does, yes. What I'm asking is how this
patch addresses the sequence I outlined above.
Explain what you mean by "build".
Using the following:
. ./oe-init-build-env build-test
<setup local.conf w/ rpm packaging and INC_RPM_IMAGE_GEN>
bitbake core-image-core
--- time passes, git pull pulls in changes ---
bitbake core-image-core
The second "build", only the changed packages will be added to the
image.
You you are using different build directories, then it doesn't re-use
anything. The purpose of this is incremental software development
within a single build directory.
You are still missing my point. The patch is broken if you change
INC_RPM_IMAGE_GEN
Only the core-image-minimal has this problem, other images won't remove the
database, the core-image-minimal removes the database to save disk space (
only saves quite a little), and I don't know whether there is a better
solution
for the core-image-minimal, maybe move the database to ${T} rather than
remove
it, and move it back to the rootfs directory at the early stage of
do_rootfs, but I don't know whether this is worth or not since this is
just used for
saving the time at the development stage, as it had told:
Robert,
The move might be the best solution since it will preserve it and make
the behavior more predictable, ie if one starts with INC_RPM_IMAGE_GEN
disabled and then enables it the package database will be available
already. It would also preserve the space in the core-image-minimal by
not keeping those database files in the image.
Please respin this patch.
Thanks
Sau!
