Smart

Mark's smart contrib branch:

To test this out querying a root filesystem on the host:

1. Ensure you are using "package_rpm" in PACKAGE_CLASSES
2. Comment out the line in core-image-minimal that removes the packaging data files
3. bitbake core-image-minimal
4. bitbake python-smartpm-native
5. bitbake -c devshell core-image-minimal
6. Within the devshell:

cd ../rootfs
export PYTHONPATH="/path/to/native/sysroot/usr/lib/python2.7/site-packages"
export RPM_ETCRPM=$PWD/etc/rpm
smart --data-dir=$PWD/var/lib/smart channel --add rpmsys type=rpm-sys name="rpmsys"
smart --data-dir=$PWD/var/lib/smart config --set rpm-root=$PWD
smart --data-dir=$PWD/var/lib/smart config --set rpm-dbpath=/var/lib/rpm

You should now be able to query the packages installed into the rootfs e.g.

smart --data-dir=$PWD/var/lib/smart query

If you add an rpm-dir channel and run smart under fakechroot (or pseudo presumably, but fakechroot is simpler for testing here) you can install and uninstall packages.
