+- version the sections in the file, put the element size in the header
+  so we can add stuff to elements in a backwards compatible way.

+- overlay package sets?  mount a read-only /usr over nfs or from the
+  virt-host and have a local package set overlaid over the read-only
+  one.  shouldn't need new features in the core package set data
+  structure, but should be just conventions on top.  we have the base
+  package set from the r/o system, the overlay set from the local
+  system and we can have an effective package set which is the merge
+  of everything from the overlay into the base set.  the effective set
+  is easy to compute and we could do it on the fly or cache it.  or
+  maybe the effective set is the on-disk representation and the
+  overlay can be computed when needed, we just keep a link back to the
+  base.
