I am now using {{- $pages := (where .Data.Pages "Type" "post") -}} which seems like it should grab all posts but not other pages. But my feeds are still split by tag:
site/posts/index.xml
site/notes/index.xml
site/pics/index.xml
etc.
I just want one major feed at site/index.xml - but that one, the one I really want, is not being created at all, just 404…
