I believe that the (highly modular) strict policy is known to be broken
in fc5/rawhide because of the file contexts ordering issue, which
requires further changes to libsemanage.  Right, Dan?  So only -targeted
or -mls are in a working state.  Possibly that -strict policy shouldn't
be included in fc5 since it is known to be broken?
