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=
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=
Added in version 245.
vlan=, bond=, bridge=, bootdev=
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.*
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.
