Yah, this is new command from 2010.  We only deal these issues every 2
or more years.  Well more abstruct solution is good as long as we know
what it does behind us.  So time to learn new trick for a old dog (=me).

As I read a bit complicated script /usr/bin/dpkg-maintscript-helper,
this seems to require us to use when the conffile change was introduced.
If I use this now, then the stable users who upgrade are handled fine
but the testing/unstable users will not be handled fine.  Instead, good
old standard trick of using md5sum check with a set of fixed values
seems to save more cases. Basically, I missed the right moment.  I will
use it for my future work but I need to think what is the best...

I now read:
 http://www.dpkg.org/dpkg/ConffileHandling
 http://wiki.debian.org/DpkgConffileHandling

Certainly, many thoughts has been merged from old trick I know. 

Let me think about this for 10 days during our spring long weekend.

Regards,

Osamu
