Here is a one-liner for private use in $ISABELLE_HOME_USER/ROOT:

   session HOL-Test! in "~~/src/HOL" = Pure + theories Nat

This works because $ISABELLE_HOME_USER is also a component.


The session layout of the main Isabelle distribution can be reconsidered 
later, when we have the transition completed.  We still have IsaMakefiles 
to be maintained in parallel to the new scheme.
