SuperUser permission for the Driver??

[Michael Stone]

We have an activity that wants superuser privilege in order to poke
kernel memory.

The real questions we should be attempting to address here include:

* Who is granting privilege to this activity?

* How are they doing so?

* How should we record the decision?

     -  My tentative answer is that we should store activities with
        different security properties in well-known directory chains
        with appropriately restricted write access.

* What kinds of abuse are these mechanisms vulnerable to?

* Whose responsibility is it to handle the error condition that the
  human operator does not, him-or-herself posess superuser privilege,
  e.g. for theft-deterrence reasons?
