I don't remember any storage in framework@Aaahh you posted a quote of me about storage and I said now that I think I know that the issue is in the storage-list.xml in the framework. I will include your apps in the next build, but for now I am focusing on a different project until M becomes more stable...
Okay, I know they changed paths in boot.img, so change them and permissive se linux if not already
That's about all, there's been fstab changes in hammered and mako but I ignored them and mine worked fine (OnePlus one)
