[yocto] OPKG configuration questions

[Glenn Schmottlach]

I have several questions regarding configuring the OPKG package management
support in my target image.

1) I'm having difficulty getting the /var/lib/opkg directory to be created
and populated with a list of installed packages.

2) I can't figure out (e.g. can find no documentation) that describe what
the "lists_dir ext /var/lib/opkg" option in the opkg.conf file does. Does
this point to where the list of installed packages should be found?

3) What is the best/preferred approach (e.g. patch, *bbappend, new recipe,
etc...) to tailor or modify the opkg.conf file (specifically the opkg
source (src) paths) that are appended to /etc/opkg/opkg.conf file by the
opkg-collatoral.bb recipe.

This is what I have done to prepare my image to include package management:

1) My image recipe inherits from core-image

2) I've configured ONLINE_PACKAGE_MANAGEMENT = "full" and confirmed that is
it set correctly via "bitbake-env -r image-nitrogen6x
ONLINE_PACKAGE_MANAGEMENT"

3) I've confirmed that IMAGE_FEATURES = "debug-tweaks package-management"

4) PACKAGE_CLASSES = "package_ipk" is configured and I see packages in my
<project>/build/tmp/deploy/ipk directory

The target boots fine and I have the appropriate opkg applications
installed (e.g. opkg, opkg-cl, opkg-key). I also have the default
/etc/opkg/opkg.conf and /etc/opkg/arch.conf installed.

There is *no* /var/lib/opkg directory and thus "opkg-cl list-installed"
returns with an error because the "opkg" directory is missing. If I
manually create it the program run successfully but doesn't list anything
(which is obvious since it is empty).

I read this post
https://lists.yoctoproject.org/pipermail/yocto/2013-June/016324.html

and confirmed that my setting are correct for IMAGE_FEATURES and
ROOT_POSTPROCESS_CMD (= "run_intercept_scriptlets;
license_create_manifest;  ssh_allow_empty_password;
rootfs_update_timestamp ;")

Can anyone offer any suggestions, recommendations, or answers to my
questions above?

Thanks for you help . . .
