Well (with small bugs) that does it, but it is brutal, since it removes
even if something has changed.

I have now added some (UNTESTED) code that:
- checks for md5sum changes and removes only if unchanged, otherwise
  simply renames it
- 00updmpa.cfg settings that are different form TL2012 defaults are
  carried over to /etc/texmf/web2c/updmap.cfg

For the second we need one change in texlive-base that it ships also
/u/s/texlive/texmf/web2c/updmap.cfg with the default settings.
THat will bei n final TL, but is not by now. 

If someone can take a look at the code in postinst that would be great.

Best wishes

Norbert
