scans the command line for options relevant to network configuration and creates configuration files for an early instance of NetworkManager run from the initial ramdisk during early boot.
OPTIONS
-c | --connections-dir path
-
Output connection directory.
-p | --persistent-connections-dir path
-
Persistent connection directory. If it exists, rd.neednet will not cause a default connection to be generated in absence of other options.
-i | --initrd-data-dir path
-
Output directory for initrd data (e.g. hostname).
-d | --sysfs-dir path
-
The sysfs mount point.
-r | --run-config-dir path
-
Output directory for config files.
-s | --stdout
-
Dump connections to standard output. Useful for debugging.

DIFFERENCES FROM THE NETWORK-LEGACY DRACUT MODULE
nm-initrd-generator
generates a set of connections that are then configured by the NetworkManager instance running in the initrd. There are some differences in behavior compared to the network-legacy dracut module:
-
•
When an interface is configured with a static address and a gateway, the network-legacy module waits that the gateway responds to arping requests before proceeding, while NetworkManager doesn't.
-
•
network-legacy configures interfaces one by one in the order in which they are announced by udev. If multiple interfaces specify a hostname (from command line or from DHCP), the one from the last interface activated wins. With NetworkManager, hostnames from command line have higher precedence over ones from DHCP, and the last that appears in the command line wins.
-
•
NetworkManager supports the
ib.pkey=PARENT.PKEY
argument to set up an Infiniband partition on IPoIB parent device
PARENT
using the specified partition key
PKEY. The partition key must be in hexadecimal notation without leading "0x", for example "ib.pkey=ib0.8004".
-
•
NetworkManager supports the
rd.ethtool=INTERFACE:AUTONEG:SPEED
kernel command line option to set up ethtool NIC configuration parameters
AUTONEG
and
SPEED. The
INTERFACE
being configured must be specified, and the other parameters are optional and can be left blank. When
SPEED
is set, duplex mode is automatically set to 'full'.
INTERFACE
accepts string values,
AUTONEG
accepts boolean values (true and false / on or off / 0 or 1), and
SPEED
accepts positive integer values.
EXIT STATUS
nm-initrd-generator
exits with status 0. It ignores unrecognized options and prints an error message if it encounters a malformed option.
