question on conffiles

[Zhao Wei <zw@debian.org>]

Hi, Mentor-helpers ;-)

As read from packaging-manual, there're two ways to handle
system specific config files, one to list them in debian/conffiles,
the other is (optionally write a /usr/bin/pkgxxxconfig to aid) to
write/modify the config file in debian/postinst, and don't list them
in debian/conffiles. My question is with the second approach, how could
dpkg determine if a /etc/pkgxxx.cfg belongs to pkgxxx? What if other
package wants to overwrite it accidentally?

Thanks alot!
