that's not the point. i was talking about privilege elevation through a
password dialog and similar.
generalizing it, a simple "may/may not" answer might be insufficient, as
the user might be able to change the situation.

well, yes. but if you standardise something for which my only option is
to ignore it, you have gained nothing.

then don't make it complicated. provide a series of hooks (through
attribute lists and similar) that allow communicating with a policy
framework.

i'm not that sure, obviously. they all meet at the mechanism to
implement a policy. it seems silly to me to have a common policy
framework in the deamons implementing the various power-related
functions and on the client side glue code that brings together the
policies of the separate apis again (it has to be presented to the user
in a coherent way).
