</I>&gt;<i> &gt; &gt;&gt;&gt; Why not making task-bs-cluster-main requires iurt instead?
</I>&gt;<i> &gt; &gt;&gt;
</I>&gt;<i> &gt; &gt;&gt; I'm not sure a virtual package in the repository is the best tool to
</I>&gt;<i> &gt; &gt;&gt; manage the list of packages that needs to be installed on the build
</I>&gt;<i> &gt; &gt;&gt; system.
</I>&gt;<i> &gt; &gt;
</I>&gt;<i> &gt; &gt; Then why are we restoring task-bs-cluster-main?
</I>&gt;<i> &gt; 
</I>&gt;<i> &gt; I think a package is also a good tool to manage package BS deps, we
</I>&gt;<i> &gt; benefit from all the conditional requirements, conflicts, virtual
</I>&gt;<i> &gt; packages, and etc from rpm
</I>&gt;<i> 
</I>&gt;<i> So i digged a little bit for this :
</I>&gt;<i> 
</I>&gt;<i> - conditional requirement -&gt; this can be done in puppet as well ( using
</I>&gt;<i> conditionals ).
</I>&gt;<i> - conflict =&gt;  we can use &quot; ensure =&gt; absent&quot; to make sure a package is
</I>&gt;<i> not there
</I>&gt;<i> - virtual packages. 
</I>&gt;<i> Indeed, this is a weak point of puppet, we need to take ( for example )
</I>&gt;<i> architecture and version in account. Yet, i think we can solve it ( even
</I>&gt;<i> if this is not as elegant as letting ) without touching puppet, or maybe
</I>&gt;<i> by patching puppet to be more virtual-name friendly in the future. 
</I>&gt;<i> - etc, I didn't found, but I guess we can add
</I>&gt;<i>   - ability to add a requires a Provides, which would indeed be the same
</I>&gt;<i> as virtual packages. 
</I>
Being a little bored while coming back to $HOME tonight, I have found a
solution for theses 2 points, patch send upstream :
