If a local package needs to add a line to /etc/services, what's the best way to do it? Should it just say grep -q fooserv || echo "fooserv 666/tcp" >> /etc/services ? /etc/services is a conffile of netbase, and from the comments it looks like local services are intended to be added at the end, but having one package change another's conffiles is apparently not something the dpkg system was originally intended to support. -- Shields, CrossLink.
