> I am confused by the characterisation of the linux filesystem as a DAG
The directory tree is a, well, tree, but if you include files than hard-links make it a DAG.
If you could hard-link directories then it wouldn't be a DAG, it'd just be a DG.

OSX allows you to hardlink directories, but still requires that the filesystem remain a DAG -- it prevents you from creating cycles.
