SYSTEMD-NETWORK-GENERATOR.SERVICE(8)         systemd-network-generator.service

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.
