I have not seen any information in regards to multi-tenancy feature packs for SharePoint 2013. Currently it seems, with the new end user licencing, when you install the Enterprise bits you can license a user for either Standard or Enterprise but not Foundation. In SharePoint 2010 you could use the Enterprise bits then create defined feature packs to give a site collection Foundation, Standard or Enterprise features. Do updated defined feature packs exist for 2013?
There is mention of them here http://www.harbar.net/articles/sp2013mt.aspx
"Feature Packs provide the ability to constrain the Features available for a given tenant. The fundamental capability isn’t changed in any way here, but of course the Features in the product have. Thus the old Feature Pack definitions for SKUs are no longer valid. A new set of feature pack definitions are required encompassing all of the new Features in SharePoint 2013."
But nothing else anywhere on the net, anyone have any ideas?
