These connections are never torn down, even when the DHCP specifications say that
they should be. This is useful/necessary when the rootfs (or another critical fs)
is mounted over this network connection, and dataloss would result if the connection
is lost.
This option defaults to off, but our initrd generator (TBD) will enable it when
applicable.

Refactor bridging support to be generic netdev support and extend it to
cover bonding as well.

Setting UseDNS=no will ignore any received DNS servers.

This adds support to generate a basic resolv.conf in /run/systemd/network.
This file will not take any effect unless a symlink is created from
/etc/resolv.conf.
Nameservers received over DHCP takes precedence over statically configured ones.
Note: /etc/resolv.conf is severely limited, so in the future we will likely
rather provide a much more powerfull nss plugin (or something to that effect),
but this should allow current users to function without any loss of
functionality.

This adds basic DHCPv4 support. Link-sense is enabled unconditionally,
but the plan is to make that configurable.
I tested this in a VM with lots of NICs and over wifi in the various
coffee shops I found this Christmas, but more testing would definitely
be appreciated.

A bridge is specified in a .netdev file with a section [Bridge]
and at least the entry Name=.
A link may be joined to a bridge if the .network applied to it has
a Bridge= entry giving the name of the bridge in its [Network] section.
We eagerly create all bridges on startup, and links are added to
bridges as soon as they both appear.

This will allow specifying more options per address than the
simple Address= entry in the [Network] section.
Preliminary support for the same functionality for [Route] sections
are added, but not yet hooked up, as more testing is needed.

This daemon listens for and configures network devices tagged with
'systemd-networkd'. By default, no devices are tagged so this daemon
can safely run in parallel with existing network daemons/scripts.
Networks are configured in /etc/systemd/network/*.network. The first .network
file that matches a given link is applied. The matching logic is similar to
the one for .link files, but additionally supports matching on interface name.
The mid-term aim is to provide an alternative to ad-hoc scripts currently used
in initrd's and for wired setups that don't change much (e.g., as seen on
servers/and some embedded systems).
Currently, static addresses and a gateway can be configured.
Example .network file:
[Match]
Name=wlp2s0
[Network]
Description=My Network
Gateway=192.168.1.1
Address=192.168.1.23/24
Address=fe80::9aee:94ff:fe3f:c618/64
