Fedora does a much more elaborate version of what I included in my
adjusted scripts. First it checks to see what type of a network device
it is and then process a specific down script for that device type.
In the Ethernet type, which is default, they check to see if dhcp is
running and if the device has a lease and if so release it. Then they have:
# we can't just delete the configured address because that address
# may have been changed in the config file since the device was
# brought up. Flush all addresses associated with this
# instance instead.
if [ -d "/sys/class/net/${REALDEVICE}" ]; then
if [ "${REALDEVICE}" = "${DEVICE}" ]; then
ip addr flush dev ${REALDEVICE} 2>/dev/null
else
ip addr flush dev ${REALDEVICE} label ${DEVICE} 2>/dev/null
fi
if [ "${SLAVE}" = "yes" -a -n "${MASTER}" ]; then
echo "-${DEVICE}" >
/sys/class/net/${MASTER}/bonding/slaves 2>/dev/null
fi
if [ "${REALDEVICE}" = "${DEVICE}" ]; then
ip link set dev ${DEVICE} down 2>/dev/null
fi
fi
After that they also check for any specific bridging rules and handle
that as well.
