+ - 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
+ http://lists.freedesktop.org/archives/systemd-devel/2014-July/021550.html
+ - add per-network Domains= settings, with a special syntax Domains=*
+ for routing all non-otherwise routed traffic to this link
+ - add UseDomains= setting to [DHCP] to add dhcp supplied domains to
+ per-interface Domains= list.
+ - expose in the API the following bits:
+ - option 15, domain name and/or option 119, search list
+ - option 12, host name and/or option 81, fqdn
+ - option 100, 101, timezone
+ - option 123, 144, geolocation
+ - option 252, configure http proxy (PAC/wpad)
+ - networkd's dhcp server should transparently pass on the DNS and
+ NTP server list it got from user configuration and its dhcp client
+ to clients. It should also pass on its own timezone information.
+ - provide a way to define a per-network interface default metric value
+ for all routes to it. possibly a second default for DHCP routes.
