I can try to make the scheme more flexible in the following way:
  - formats will always and up in VARTEXMF if this is set, else in TEXMFMAIN
    (I think that we all agree on this)
  - config files are no longer copied automatically; I make this a step that
    the user (or the installation procedure) has to take explicitly
  - I introduce a special variable TEXMFCONFIG (argh, this is close to
    TEXMFCNF and TEXCONFIG...), so people are not forced to use
    either TEXMFLOCAL or VARTEXMF for this. TeX Live's setup can use
    TEXMFCONFIG=$VARTEXMF is this is what everybody wants.

Sounds good?
