  We study gauged five-dimensional supergravity on the interval [0,\pi R]. We
find a set of boundary conditions with respect to which the theory is locally
supersymmetric. For theories with detuned brane tensions (\Lambda_4<0), we show
that these boundary conditions can be used to spontaneously break global
supersymmetry. For the original, tuned Randall-Sundrum scenario (\Lambda_4=0),
we prove that the locally supersymmetric boundary conditions are also globally
supersymmetric. We lift the theory from [0,\pi R] to S^1 and R, with arbitrary
twists for the fermions, and cast these results in the language of the
Scherk-Schwarz mechanism.
