In the class of (0,2) heterotic compactifications which has been constructed in the framework of gauged linear sigma models the Calabi-Yau varieties X are realized as complete intersections of hypersurfaces in toric varieties IP and the corresponding gauge bundles (or more generally gauge sheaves) E are defined by some short exact sequences. We show that there is yet another degree of freedom in resolving singularities in such models which is related to the possible choices of nef partitions of the anticanonical divisors in Gorenstein Fano toric varieties IP.
