>look my debian/network-config/usr/share/doc/changelog.Debian.gz and change.gz (upstream) and NEWS and README.
override_dh_installchangelogs:
dh_installchangelogs ChangeLog
or whatever should do the trick
(sorry I can't try, I'm on a hurry)
but a file named debian/network-config.changelogs is far better for me.
cheers,
