IPv4 link-local addresses (zeroconf) are

only applicable on the 'inet' address family

[ "X$ADDRFAM" != "Xinet" ] && exit 0

However there are some methods where it doesn't

make any sense to configure an IPv4LL address

not on loopback

[ "X$METHOD" = "Xloopback" ] && exit 0

not on ppp or wvdial either

[ "X$METHOD" = "Xppp" ] && exit 0 [ "X$METHOD" = "Xwvdial" ] && exit 0

The administrator may have blacklisted interfaces

or only want zeroconf in a fallback situation

[ -f /etc/default/zeroconf ] && . /etc/default/zeroconf

[ -n "$DISABLE" ] && exit 0

for BLACK in $IFBLACKLIST; do case $IFACE in $BLACK) exit 0 ;; esac done

should we only allocate an address if we do not already have one?

if [ -n "$FALLBACK" ]; then /bin/ip addr show $IFACE scope global | grep -q "inet" IP=$? if [ $IP -eq 0 ]; then /bin/ip route add 169.254.0.0/16 dev $IFACE exit 0 fi fi

otherwise, run if we aren't already going

if [ ! -r /var/run/zeroconf.$IFACE.pid ]; then /usr/sbin/zeroconf -i $IFACE fi

exit 0
