+    Remove the setting for TFMFONTS if we have kpathsea, because
+    kpathsea can find TFM fonts anyway.
+
+    If we don't lily will want to make tfms for cmr fonts, even if
+    there is a :: entry in the TFMFONTS path.
+
+    This will fail if a user has special fonts (outside of feta) that
+    can not be found by kpath.
+
+    If TFMFONTS is unset, TFMs of feta will be generated on the
+    fly. The risk is that this will cause checksum mismatch errors,
+    but MF is reasonably deterministic (so we hope not).
+
+    The advantage is that the PK font will also be generated under
+    /var/texmf/fonts, reducing clutter and compilation time.
