"Support:" option in prjconf is ignored for docker/podman build

[fcrozat]

Unlike kiwi style build, Support: directives are ignored when building containers with Docker / Podman.

I have to use:

%if %_repository == "images"
Support: containment-rpm
%else
%if %_repository == "containerfile" 
Substitute: system-packages:podman podman buildah createrepo_c release-compare skopeo umoci containment-rpm
%endif
%endif

Does Required instead work?

That Support is used at all in kiwi builds is for some backwards compat only:

obs-build/Build.pm

Line 860 in c6092e7

push @sysdeps, @{$config->{'support'}} if $buildtype eq 'kiwi-image' || $buildtype eq 'kiwi-product'; # compat to old versions

(IMO we need some build type specific Support)

Yes, it works fine.
