archive the package database after the rootfs has been put together as
*rootfs-pkdbfs.tar.gz, and put it into the deploy folder.
This creates a snapshot of the package mangers state at the point in
time when all dependencies have been resolved and installed; which
could be used by "extension images" to built upon.

set the package-database of a "lower image" to unpack and build upon
when installing packages for the current image. This way a lean image
will be created, which only holds the packages that are not already
present in the lower image.
An image build such could then be used with overlayfs or systemd-
sysext to extend the "lower image" on demand; for development purposes
on a device running the "lower image" in RO mode for example.
A configuration could look as follows:
some-core-image.bb
inherit image
IMAGE_GEN_PKGDBFS = "1"
extending-image.bb
inherit image
IMAGE_BASE_PKGDB = "some-core-image"

systemd-sysext can load a raw-image containing usr/ and opt/ folders
to mount them as RO overlay over the rootfs, to "extend" the systems.
This class provides the necessary changes/additions to the enclosed
file-system so that systemd-sysext accepts the extension for "merge"
into the rootfs.
With such an created image, placed into the correct folder (see [1]),
`systemd-sysext list` should be able to list the "extension" and
`systemd-sysext merge` should enable the overlay. On both commands a
preceding "SYSTEMD_LOG_LEVEL=debug" can aide in figuring out what is
amiss.
The strict name checking systemd-sysext does against the name of
extension-release.NAME file, is disabled, as there is only one such in
the resulting image. This is done to allow a user to freely rename the
resulting image file.
Note that for e.g. squashfs, the kernel needs CONFIG_SQUASHFS_XATTR=y

Hoi Alexandre,
and thanks again for pointing out the build-failure.
but since the recent test restructuring didn't help either... i could use help to reproduce what the autobuilder is *exactly* doing :-S
because when running the tests directly, they pass (see below)
my guess is that in the whole/complete test-run the autobuilder pulls sth out of the (sstate) cache instead of actually building the image with the different feature-set?
or could it be some other side-effect when the whole test-set is run?
i had based the testcases for this patch-set on the others already present - so the same logical flow of building images is used (or did i miss sth?)
any hints/pointers/thoughts would be greatly appreciated :-)
gruß
Johannes
