update gitignore

resolved: add daemon to manage resolv.conf Also remove the equivalent functionality from networkd.

networkd: manager - read fallback DNS servers from config file We will still use the compiled-in defaults if no DNS entry exists in the config file.

networkd-wait-online: drop config file and add commandline options instead

networkd-wait-online: improve interoptability and enable by default To make sure we don't delay boot on systems where (some) network links are managed by someone else we don't block if something else has successfully brought up a link. We will still block until all links we are aware of that are managed by networkd have been configured, but if no such links exist, and someone else have configured a link sufficiently that it has a carrier, it may be that the link is ready so we should no longer block. Note that in all likelyhood the link is not ready (no addresses/routes configured), so whatever network managment daemon configured it should provide a similar wait-online service to block network-online.target until it is ready. The aim is to block as long as we know networking is not fully configured, but no longer. This will allow systemd-networkd-wait-online.service to be enabled on any system, even if we don't know whether networkd is the main/only network manager. Even in the case networking is fully configured by networkd, the default behavior may not be sufficient: if two links need to be configured, but the first is fully configured before the second one appears we will assume the network is up. To work around that, we allow specifying specific devices to wait for before considering the network up. This unit is enabled by default, just like systemd-networkd, but will only be pulled in if anyone pulls in network-online.target.

networkd: netdev - allow filtering on kernel cmdline, host and virt

networkd: add a basic network daemon 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
