systemd systemd-network-generator.service 8 systemd-network-generator.service systemd-network-generator Generate network configuration from the kernel command line systemd-network-generator.service /usr/lib/systemd/systemd-network-generator systemd-network-generator.service is a system service that translates ip= and related settings on the kernel command line (see below) into systemd.network5, systemd.netdev5, and systemd.link5 configuration files understood by systemd-networkd.service8 and systemd-udevd.service8. Files are generated in /run/systemd/network/. Note: despite the name, this generator executes as a normal systemd service and is not an implementation of the systemd.generator7 concept. This tool understands the following options: ip= nameserver= rd.route= rd.peerdns= Translated into systemd.network5 files. In addition to the parameters dracut.cmdline7 defines the ip= option accepts the special value link-local. If selected, the network interfaces will be configured for link-local addressing (IPv4LL, IPv6LL) only, DHCP or IPv6RA will not be enabled. ifname= net.ifname_policy= Translated into systemd.link5 files. vlan= bond= bridge= bootdev= Translated into systemd.netdev5 files. See dracut.cmdline7 and systemd-udevd.service8 for option syntax and details. systemd-network-generator supports the service credentials logic as implemented by ImportCredential=/LoadCredential=/SetCredential= (see systemd.exec5 for details). The following credentials are used when passed in: network.netdev.* network.link.* network.network.* These credentials should contain valid systemd.netdev5, systemd.link5, systemd.network5 configuration data. From each matching credential a separate file is created. Example: a passed credential network.link.50-foobar will be copied into a configuration file 50-foobar.link. Note that the resulting files are created world-readable, it's hence recommended to not include secrets in these credentials, but supply them via separate credentials directly to systemd-networkd.service. Note that by default the systemd-network-generator.service unit file is set up to inherit the these credentials from the service manager. systemd1 systemd-networkd.service8 dracut8
