[tex-live] lambda, omega, latex.ini

[Karl Berry]

    As for texmf-dist/tex/latex/config/latex.ini, can I change it on p4 depot
    following Thomas' suggestion:
     \input pdftexconfig\pdfoutput=0
     \scrollmode
     \input latex.ini

    or should we leave it at it was? Just to avoid any hot discussion...

Avoid?  Surely you jest :).

As we've discussed at length, I don't think either of the above (leave
it alone or just use pdftex "bare") is right.  I think we should play
the preserve-and-undefine-primitives trick.  I don't see any serious
downside, it's just ugly -- but compatible.  Next year we can be
incompatible.  teTeX can be incompatible this year.

Specifically, I think latex.ini (and others) should say \input
pdftex-dvi.tex, where pdftex-dvi.tex is the following.

Have we reached consensus on this?
