I reported it here: http://tracker.luatex.org/view.php?id=965

The response was that no problem was seen. But do get this warning. So
I investigated some more and discovered a strange thing: when luatex
is run from current directory, it loads only myfont.ofm, but when it
is run not from current directory, it tries to load also myfont.ovf
and cmb10.tfm (for the complete explanation see

Why luatex loads different files depending from which directory it is
run? Is it something in TeX Live that causes this difference in
behavior, or it is the problem with luatex?
