Not necessary. If the DHCP client uses the dbus to report results, then a
program like NetworkManager can follow those results and kick off a link
local allocation when the DHCP client reports that it can't get an address.
Later on, when the DHCP client (which is still trying to get an address)
finally gets an address, NetworkManager can release the link-local address.
Personally, my preference has always been to run the link-local and DHCP
configurations as independent processes, because I think that bringing the
link-local address up and down in response to DHCP state changes is more
likely to create instability than stability.
