# 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
               is hence recommended to not include secrets in these
               credentials, but to supply them via separate credentials
               directly to systemd-networkd.service(8).
    
               Added in version 256.
    
           Note that by default the systemd-networkd.service(8) service is
           set up to inherit the these credentials from the service manager.
