NAME
systemd-network-generator.service, systemd-network-generator - Generate network configuration from the kernel command line
SYNOPSIS
systemd-network-generator.service /usr/lib/systemd/systemd-network-generator
DESCRIPTION
systemd-network-generator.service is a system service that translates ip= and related settings on the kernel command line (see below) into systemd.network(5), systemd.netdev(5), and systemd.link(5) configuration files understood by systemd- networkd.service(8) and systemd-udevd.service(8). 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.generator(7) concept.
KERNEL COMMAND LINE OPTIONS
This tool understands the following options: ip=, nameserver=, rd.route=, rd.peerdns= Translated into systemd.network(5) files. In addition to the parameters dracut.cmdline(7) 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. Added in version 245. ifname=, net.ifname_policy= Translated into systemd.link(5) files. Added in version 245. vlan=, bond=, bridge=, bootdev= Translated into systemd.netdev(5) files. Added in version 245. See dracut.cmdline(7) and systemd-udevd.service(8) for option syntax and details.
CREDENTIALS
systemd-network-generator supports the service credentials logic as implemented by ImportCredential=/LoadCredential=/SetCredential= (see systemd.exec(5) for details). The following credentials are used when passed in: network.conf.*, network.link.*, network.netdev.*, network.network.* These credentials should contain valid networkd.conf(5), systemd.link(5), systemd.netdev(5), systemd.network(5) 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. Added in version 256. Note that by default the systemd-network-generator.service unit file is set up to inherit the these credentials from the service manager.
