Comment on ``Exact bosonization for an interacting Fermi gas in arbitrary dimensions''

This a comment on arXiv:0907.3243v2. We demonstrate that the method proposed by Efetov {\it et. al.} is just a reformulation of the Blankenbeckler, Scalapino, and Sugar approach and thus it contains exactly the same sign problem, including the dependence of the sign on the smoothness of the paths.
