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.
