  The MSSM potential can have unphysical minima deeper than the physically
acceptable one. We point out that their presence is quite generic in SO(10)
unification with supergravity mediated soft terms. However, at least for
moderate values of tan\beta, the physically acceptable vacuum has a life-time
longer than the universe age. Furthermore, by discussing the evolution of the
universe in an inflationary scenario, we show that the correct vacuum is the
natural expectation. This is not the tendency in more general cases. Even in
the SO(10) case, the weak assumptions necessary for this may prevent to use the
\tilde\nu h^u direction for baryogenesis a la Affleck-Dine.
