systemd-network-generator.service, systemd-network-generator — Generate network configuration from the kernel command line
systemd-network-generator.service
/usr/lib/systemd/systemd-network-generator
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.
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.
ifname=, net.ifname-policy=¶Translated into systemd.link(5) files.
vlan=, bond=, bridge=, bootdev=¶Translated into systemd.netdev(5) files.
See dracut.cmdline(7) and systemd-udevd.service(8) for option syntax and details.
