- ipv4ll with multiple interfaces doesn't work when both dhcp and
ipv4ll is used. for some reasons the kernel will currently pick an
ipv4ll source address to reach non-ipv4ll gateways.
- - dhcp and ipv4ll should probably be skipped for "lo" devices, even
- if the user has a catchall .network file installed, that might
- theoretically match it.
- the DHCP lease data (such as NTP/DNS) is still made available when
a carrier is lost on a link. It should be removed instantly.
- .network setting that allows overriding of the hostname to send to the dhcp server
