I'm not sure what it is you're saying are DAGs, but it sounds as though
you're talking about the device configuration tree.  Well, this sure
doesn't look very DAGlike to me:

## SBus expander box
xbox*   at sbus? slot ? offset ?
sbus*   at xbox?

(Those lines are taken from the sparc GENERIC config.)

The tree of devices actually located during autoconf, that's a DAG -
but it's a tree, so presumably that's not what you're talking about.
