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.
