trim package imports

[nkraetzschmar]

throw out all packages from the import set that do not match any entry in a pkg.include file in gardenlinux

Warning

This may break non gardenlinux distros using our repo (e.g. gardenlinux-ccloud)
DO NOT merge till this is evaluated!

[nkraetzschmar]

cat $(find gardenlinux/gardenlinux/features -name pkg.include) | grep -v '^[$#]' | sort -u > used_pkgs
cat gardenlinux/repo/package-imports | grep -v '^[$#]' > imported_pkgs
join -v 1 imported_pkgs used_pkgs > pkg_trim
cat pkg_trim | while read pkg; do gsed -i "/^$pkg$/d" package-imports; done

Please keep in mind that some included packages might be needed, but are not included anywhere in the GL features.
They are used, for example, in gardenlinux-ccloud. One example would be sssd.
