A systematic way of generating sets of local boundary conditions on the gauge fields in a path integral is presented. These boundary conditions are suitable for one-loop effective action calculations on manifolds with a boundary and for quantum cosmology. For linearized gravity, the general procedure described here leads to new sets of boundary conditions.
