Bug#637889: /etc/init.d/tayga does not set up the interfaces (patch attached)

Package: tayga
Version: 0.9.2
Severity: normal

After installing tayga and creating its configuration file it is necessary to manually run many commands to create the tun device and to add the addresses. From the program's web page:

# tayga --mktun
# ip link set nat64 up
# ip addr add 192.168.0.1 dev nat64 (replace with your router's IPv4 address)
# ip addr add 2001:db8:1::1 dev nat64 (replace with your router's IPv6 address)
# ip route add 192.168.255.0/24 dev nat64
# ip route add 2001:db8:1:ffff::/96 dev nat64
# tayga

The attached patch reads /etc/tayga.conf and runs those commands. It also destroys the tunnel when tayga is stopped.
