This is symlink is not unneeded. It is required if you run systemd.
Usually you would create it by running
"systemctl enable avahi-daemon.service" in the package postinst.
"systemctl enable" will create the same set of shortcuts as are shipped
in the package directly.
But unfortunately in Debian we couldn't decide yet, which init system to
support, so I can't rely on systemctl being available during
installation time of avahi-daemon.
If then later on a user installs systemd, avahi-daemon would no longer
start automatically, because those symlinks would be missing and he
would have to remember to run "systemctl enable avahi-daemon.service"
manually.

That's why I decided to ship the symlinks in the package directly.
I basically do the same in the rsyslog and hal package.
This is not a great solution for the problem, but as said, I can't rely
on systemctl being available during installation time of avahi-daemon,
unless I make avahi-daemon depend on systemd.

Hope this clarifies this misunderstanding.
