  We analyze several aspects of R-symmetry and supersymmetry breaking in
generalized O'Raifeartaigh models with non-canonical Kahler potential. Some
conditions on the Kahler potential are derived in order for the
non-supersymmetric vacua to be degenerate. We calculate the Coleman-Weinberg
(CW) effective potential for general quiral non-linear sigma models and then
study the 1-loop quantum corrections to the pseudo-moduli space. For
R-symmetric models, the quadratic dependence of the CW potential with the
ultraviolet cutoff scale disappears. We also show that the conditions for
R-symmetry breaking are independent of this scale and remain unchanged with
respect to those of canonical models. This is, R-symmetry can be broken when
generic R-charge assignments to the fields are made, while it remains unbroken
when only fields with R-charge 0 and 2 are present. We further show that these
models can keep the runaway behavior of their canonical counterparts and also
new runaway directions can be induced. Due to the runaway directions, the
non-supersymmetric vacua is metastable.
