We can known the image's RDEPENDS outside the build environment, and
can use a third part installer such as anaconda to install the packages.
It's hard to get the ROOTFS_POSTPROCESS_COMMAND outside the build
environment, now the shell function can be added to postinst, and will
show a warning for the python function. We have two python functions
atm: write_package_manifest and write_image_manifest, we don't need them
in the binary pkg.
* Brief design:
- Set the RDEPENDS and create the package as other regular recipes.
- Translate the ROOTFS_POSTPROCESS_COMMAND to postinst
do_install[postfuncs] += "get_rootfs_postprocess_command"
The get_rootfs_postprocess_command() will emit the shell script to
/usr/share/${PN}, and the pkg_postinst_${PN} will run it when do the
install.
* Fixed:
RDEPENDS -> RDEPENDS_${PN}, the similar to RRECOMMENDS
* Tested on rpm, dep and ipk
* TODO:
- Create the binary pkg optionally rather than default ?
[YOCTO #6463]
Interesting approach.
Image binaries were created before
poky-commit:6706c7bdd2de6e0e447d90062e74a718a8d31778,
but this feature was removed.
A similiar approach has been rejected before:

I ended up with a fork of image.bbclass for images I needed available as
meta-packages.
Thanks for the comment, I didn't know that you had done such things before.
I'd like to add another bbclass to do this if this isn't accepted.

Why are you commenting out these vars ?
Perhaps it would be better to fix the ROOTFS_POSTPROCESS_COMMANDs, and rely on a
sane environment ?
They are not available when outside the build env, for example, when you run the
smart install core-image-minimal.rpm on the target.

If the ROOTFS_POSTPROCESS_COMMANDs do follow the same rules as other
postinstalls, you could potentially defer executing to first boot when errors
occur. (run-postinst)
Yes, we need fix here a little.
