DRACUT.CMDLINE

NAME

dracut.cmdline − dracut kernel command line options

DESCRIPTION

The root device used by the kernel is specified in the boot configuration file on the kernel command line, as always.

The traditional root=/dev/sda1 style device specification is allowed, but not encouraged. The root device should better be identified by LABEL or UUID. If a label is used, as in root=LABEL=<label_of_root> the initramfs will search all available devices for a filesystem with the appropriate label, and mount that device as the root filesystem. root=UUID=<uuidnumber> will mount the partition with that UUID as the root filesystem.

In the following all kernel command line parameters, which are processed by dracut, are described.

"rd.*" parameters mentioned without "=" are boolean parameters. They can be turned on/off by setting them to {0|1}. If the assignment with "=" is missing "=1" is implied. For example rd.info can be turned off with rd.info=0 or turned on with rd.info=1 or rd.info. The last value in the kernel command line is the value, which is honored.

Standard
init=<path to real init>

specify the path to the init programm to be started after the initramfs has finished

root=<path to blockdevice>

specify the block device to use as the root filesystem.

Example.

root=/dev/sda1
root=/dev/disk/by−path/pci−0000:00:1f.1−scsi−0:0:1:0−part1
root=/dev/disk/by−label/Root
root=LABEL=Root
root=/dev/disk/by−uuid/3f5ad593−4546−4a94−a374−bcfb68aa11f7
root=UUID=3f5ad593−4546−4a94−a374−bcfb68aa11f7
root=PARTUUID=3f5ad593−4546−4a94−a374−bcfb68aa11f7

rootfstype=<filesystem type>

"auto" if not specified.

Example.

rootfstype=ext3

rootflags=<mount options>

specify additional mount options for the root filesystem. If not set, /etc/fstab of the real root will be parsed for special mount options and mounted accordingly.

force mounting / and /usr (if it is a separate device) read−only. If none of ro and rw is present, both are mounted according to /etc/fstab.

force mounting / and /usr (if it is a separate device) read−write. See also ro option.

rootfallback=<path to blockdevice>

specify the block device to use as the root filesystem, if the normal root cannot be found. This can only be a simple block device with a simple file system, for which the filesystem driver is either compiled in, or added manually to the initramfs. This parameter can be specified multiple times.

rd.auto rd.auto=1

enable autoassembly of special devices like cryptoLUKS, dmraid, mdraid or lvm. Default is off as of dracut version >= 024.

rd.fstab=0

do not honor special mount options for the root filesystem found in /etc/fstab of the real root.

resume=<path to resume partition>

resume from a swap partition

Example.

resume=/dev/disk/by−path/pci−0000:00:1f.1−scsi−0:0:1:0−part1
resume=/dev/disk/by−uuid/3f5ad593−4546−4a94−a374−bcfb68aa11f7
resume=UUID=3f5ad593−4546−4a94−a374−bcfb68aa11f7

rd.skipfsck

skip fsck for rootfs and /usr. If you’re mounting /usr read−only and the init system performs fsck before remount, you might want to use this option to avoid duplication.

Misc
rd.driver.blacklist=<drivername>[,<drivername>,...]

do not load kernel module <drivername>. This parameter can be specified multiple times.

rd.driver.pre=<drivername>[,<drivername>,...]

force loading kernel module <drivername>. This parameter can be specified multiple times.

rd.driver.post=<drivername>[,<drivername>,...]

force loading kernel module <drivername> after all automatic loading modules have been loaded. This parameter can be specified multiple times.

rd.retry=<seconds>

specify how long dracut should retry the initqueue to configure devices. The default is 30 seconds. After 2/3 of the time, degraded raids are force started. If you have hardware, which takes a very long time to announce its drives, you might want to extend this value.

rd.timeout=<seconds>

specify how long dracut should wait for devices to appear. The default is 0, which means forever. Note that this timeout should be longer than rd.retry to allow for proper configuration.

rd.noverifyssl

accept self−signed certificates for ssl downloads.

rd.ctty=<terminal device>

specify the controlling terminal for the console. This is useful, if you have multiple "console=" arguments.

rd.nocmdline

Skip built−in commandline arguments

Debug
If you are dropped to an emergency shell, the file /run/initramfs/rdsosreport.txt is created, which can be safed to a (to be mounted by hand) partition (usually /boot) or a USB stick. Additional debugging info can be produced by adding rd.debug to the kernel command line. /run/initramfs/rdsosreport.txt contains all logs and the output of some tools. It should be attached to any report about dracut problems.

rd.info

print informational output though "quiet" is set

rd.shell

allow dropping to a shell, if root mounting fails

rd.debug

set −x for the dracut shell. If systemd is active in the initramfs, all output is logged to the systemd journal, which you can inspect with "journalctl −ab". If systemd is not active, the logs are written to dmesg and /run/initramfs/init.log. If "quiet" is set, it also logs to the console.

rd.memdebug=[0−3]

Print memory usage info at various points, set the verbose level from 0 to 3.

Higher level means more debugging output:

0 − no output
1 − partial /proc/meminfo
2 − /proc/meminfo
3 − /proc/meminfo + /proc/slabinfo

rd.break

drop to a shell at the end

rd.break={cmdline|pre−udev|pre−trigger|initqueue|pre−mount|mount|pre−pivot|cleanup}

drop to a shell on defined breakpoint

rd.udev.info

set udev to loglevel info

rd.udev.debug

set udev to loglevel debug

I18N
rd.vconsole.keymap=<keymap base file name>

keyboard translation table loaded by loadkeys; taken from keymaps directory; will be written as KEYMAP to /etc/vconsole.conf in the initramfs.

Example.

rd.vconsole.keymap=de−latin1−nodeadkeys

rd.vconsole.keymap.ext=<list of keymap base file names>

list of extra keymaps to bo loaded (sep. by space); will be written as EXT_KEYMAP to /etc/vconsole.conf in the initramfs

rd.vconsole.unicode

boolean, indicating UTF−8 mode; will be written as UNICODE to /etc/vconsole.conf in the initramfs

rd.vconsole.font=<font base file name>

console font; taken from consolefonts directory; will be written as FONT to /etc/vconsole.conf in the initramfs.

Example.

rd.vconsole.font=LatArCyrHeb−16

rd.vconsole.font.map=<console map base file name>

see description of −m parameter in setfont manual; taken from consoletrans directory; will be written as FONT_MAP to /etc/vconsole.conf in the initramfs

rd.vconsole.font.unimap=<unicode table base file name>

see description of −u parameter in setfont manual; taken from unimaps directory; will be written as FONT_UNIMAP to /etc/vconsole.conf in the initramfs

rd.locale.LANG=<locale>

taken from the environment; if no UNICODE is defined we set its value in basis of LANG value (whether it ends with ".utf8" (or similar) or not); will be written as LANG to /etc/locale.conf in the initramfs.

Example.

rd.locale.LANG=pl_PL.utf8

rd.locale.LC_ALL=<locale>

taken from the environment; will be written as LC_ALL to /etc/locale.conf in the initramfs

LVM
rd.lvm=0

disable LVM detection

rd.lvm.vg=<volume group name>

only activate the volume groups with the given name. rd.lvm.vg can be specified multiple times on the kernel command line.

rd.lvm.lv=<logical volume name>

only activate the logical volumes with the given name. rd.lvm.lv can be specified multiple times on the kernel command line.

rd.lvm.conf=0

remove any /etc/lvm/lvm.conf, which may exist in the initramfs

crypto LUKS
rd.luks=0

disable crypto LUKS detection

rd.luks.uuid=<luks uuid>

only activate the LUKS partitions with the given UUID. Any "luks−" of the LUKS UUID is removed before comparing to <luks uuid>. The comparisons also matches, if <luks uuid> is only the beginning of the LUKS UUID, so you don’t have to specify the full UUID. This parameter can be specified multiple times.

rd.luks.allow−discards=<luks uuid>

Allow using of discards (TRIM) requests for LUKS partitions with the given UUID. Any "luks−" of the LUKS UUID is removed before comparing to <luks uuid>. The comparisons also matches, if <luks uuid> is only the beginning of the LUKS UUID, so you don’t have to specify the full UUID. This parameter can be specified multiple times.

rd.luks.allow−discards

Allow using of discards (TRIM) requests on all LUKS partitions.

rd.luks.crypttab=0

do not check, if LUKS partition is in /etc/crypttab

crypto LUKS − key on removable device support
rd.luks.key=<keypath>:<keydev>:<luksdev>

keypath is a path to key file to look for. It’s REQUIRED. When keypath ends with .gpg it’s considered to be key encrypted symmetrically with GPG. You will be prompted for password on boot. GPG support comes with crypt−gpg module which needs to be added explicitly.

keydev is a device on which key file resides. It might be kernel name of devices (should start with "/dev/"), UUID (prefixed with "UUID=") or label (prefix with "LABEL="). You don’t have to specify full UUID. Just its beginning will suffice, even if its ambiguous. All matching devices will be probed. This parameter is recommended, but not required. If not present, all block devices will be probed, which may significantly increase boot time.

If luksdev is given, the specified key will only be applied for that LUKS device. Possible values are the same as for keydev. Unless you have several LUKS devices, you don’t have to specify this parameter. The simplest usage is:

Example.

rd.luks.key=/foo/bar.key

As you see, you can skip colons in such a case.

Note
dracut pipes key to cryptsetup with −d − argument, therefore you need to pipe to crypsetup luksFormat with −d −, too!

Here follows example for key encrypted with GPG:

gpg −−quiet −−decrypt rootkey.gpg | \
cryptsetup −d − −v −−cipher serpent−cbc−essiv:sha256 \
−−key−size 256 luksFormat /dev/sda3

If you use plain keys, just add path to −d option:

cryptsetup −d rootkey.key −v −−cipher serpent−cbc−essiv:sha256 \
−−key−size 256 luksFormat /dev/sda3

MD RAID
rd.md=0

disable MD RAID detection

rd.md.imsm=0

disable MD RAID for imsm/isw raids, use DM RAID instead

rd.md.ddf=0

disable MD RAID for SNIA ddf raids, use DM RAID instead

rd.md.conf=0

ignore mdadm.conf included in initramfs

rd.md.waitclean=1

wait for any resync, recovery, or reshape activity to finish before continuing

rd.md.uuid=<md raid uuid>

only activate the raid sets with the given UUID. This parameter can be specified multiple times.

DM RAID
rd.dm=0

disable DM RAID detection

rd.dm.uuid=<dm raid uuid>

only activate the raid sets with the given UUID. This parameter can be specified multiple times.

FIPS
rd.fips

enable FIPS

boot=<boot device>

specify the device, where /boot is located.

Example.

boot=/dev/sda1
boot=/dev/disk/by−path/pci−0000:00:1f.1−scsi−0:0:1:0−part1
boot=UUID=<uuid>
boot=LABEL=<label>

rd.fips.skipkernel

skip checksum check of the kernel image. Useful, if the kernel image is not in a separate boot partition.

Network

Important
It is recommended to either bind an interface to a MAC with the ifname argument, or to use the systemd−udevd predictable network interface names.

Predictable network interface device names based on:

• firmware/bios−provided index numbers for on−board devices

• firmware−provided pci−express hotplug slot index number

• physical/geographical location of the hardware

• the interface’s MAC address

See: http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames

Two character prefixes based on the type of interface:

ethernet

wlan

wwan

Type of names:

o<index>

on−board device index number

s<slot>[f<function>][d<dev_id>]

hotplug slot index number

x<MAC>

MAC address

[P<domain>]p<bus>s<slot>[f<function>][d<dev_id>]

PCI geographical location

[P<domain>]p<bus>s<slot>[f<function>][u<port>][..][c<config>][i<interface>]

USB port number chain

All multi−function PCI devices will carry the [f<function>] number in the device name, including the function 0 device.

When using PCI geography, The PCI domain is only prepended when it is not 0.

For USB devices the full chain of port numbers of hubs is composed. If the name gets longer than the maximum number of 15 characters, the name is not exported. The usual USB configuration == 1 and interface == 0 values are suppressed.

PCI ethernet card with firmware index "1"

• eno1

PCI ethernet card in hotplug slot with firmware index number

• ens1

PCI ethernet multi−function card with 2 ports

• enp2s0f0

• enp2s0f1

PCI wlan card

• wlp3s0

USB built−in 3G modem

• wwp0s29u1u4i6

USB Android phone

• enp0s29u1u2

ip={dhcp|on|any|dhcp6|auto6|ibft}

auto6

IPv6 autoconfiguration

dhcp6

IPv6 DHCP

ibft

iBFT autoconfiguration

ip=<interface>:{dhcp|on|any|dhcp6|auto6}[:[<mtu>][:<macaddr>]]

This parameter can be specified multiple times.

dhcp|on|any|dhcp6

get ip from dhcp server on a specific interface

auto6

do IPv6 autoconfiguration

optionally set <macaddr> on the <interface>. This cannot be used in conjunction with the ifname argument for the same <interface>.

ip=<client−IP>:[<peer>]:<gateway−IP>:<netmask>:<client_hostname>:<interface>:{none|off|dhcp|on|any|dhcp6|auto6|ibft}:[:[<mtu>][:<macaddr>]]

explicit network configuration. If you want do define a IPv6 address, put it in brackets (e.g. [2001:DB8::1]). This parameter can be specified multiple times. <peer> is optional and is the address of the remote endpoint for pointopoint interfaces and it may be followed by a slash and a decimal number, encoding the network prefix length.

optionally set <macaddr> on the <interface>. This cannot be used in conjunction with the ifname argument for the same <interface>.

ip=<client−IP>:[<peer>]:<gateway−IP>:<netmask>:<client_hostname>:<interface>:{none|off|dhcp|on|any|dhcp6|auto6|ibft}[:[<dns1>][:<dns2>]]

ifname=<interface>:<MAC>

Assign network device name <interface> (ie "bootnet") to the NIC with MAC <MAC>.

Warning
Do not use the default kernel naming scheme for the interface name, as it can conflict with the kernel names. So, don’t use "eth[0−9]+" for the interface name. Better name it "bootnet" or "bluesocket".

bootdev=<interface>

specify network interface to use routing and netroot information from. Required if multiple ip= lines are used.

BOOTIF=<MAC>

specify network interface to use routing and netroot information from.

rd.bootif=0

Disable BOOTIF parsing, which is provided by PXE

specify nameserver(s) to use

biosdevname=0

boolean, turn off biosdevname network interface renaming

rd.neednet=1

boolean, bring up network even without netroot set

vlan=<vlanname>:<phydevice>

Setup vlan device named <vlanname> on <phydeivce>. We support the four styles of vlan names: VLAN_PLUS_VID (vlan0005), VLAN_PLUS_VID_NO_PAD (vlan5), DEV_PLUS_VID (eth0.0005), DEV_PLUS_VID_NO_PAD (eth0.5)

bond=<bondname>[:<bondslaves>:[:<options>]]

Setup bonding device <bondname> on top of <bondslaves>. <bondslaves> is a comma−separated list of physical (ethernet) interfaces. <options> is a comma−separated list on bonding options (modinfo bonding for details) in format compatible with initscripts. If <options> includes multi−valued arp_ip_target option, then its values should be separated by semicolon. Bond without parameters assumes bond=bond0:eth0,eth1:mode=balance−rr

team=<teammaster>:<teamslaves>

Setup team device <teammaster> on top of <teamslaves>. <teamslaves> is a comma−separated list of physical (ethernet) interfaces.

bridge=<bridgename>:<ethnames>

Setup bridge <bridgename> with <ethnames>. <ethnames> is a comma−separated list of physical (ethernet) interfaces. Bridge without parameters assumes bridge=br0:eth0

NFS
root=[<server−ip>:]<root−dir>[:<nfs−options>]

mount nfs share from <server−ip>:/<root−dir>, if no server−ip is given, use dhcp next_server. if server−ip is an IPv6 address it has to be put in brackets, e.g. [2001:DB8::1]. NFS options can be appended with the prefix ":" or "," and are seperated by ",".

root=nfs:[<server−ip>:]<root−dir>[:<nfs−options>], root=nfs4:[<server−ip>:]<root−dir>[:<nfs−options>], root={dhcp|dhcp6}

root=dhcp alone directs initrd to look at the DHCP root−path where NFS options can be specified.

Example.

root−path=<server−ip>:<root−dir>[,<nfs−options>]
root−path=nfs:<server−ip>:<root−dir>[,<nfs−options>]
root−path=nfs4:<server−ip>:<root−dir>[,<nfs−options>]

root=/dev/nfs nfsroot=[<server−ip>:]<root−dir>[:<nfs−options>]

Deprecated! kernel Documentation_/filesystems/nfsroot.txt_ defines this method. This is supported by dracut, but not recommended.

rd.nfs.domain=<NFSv4 domain name>

Set the NFSv4 domain name. Will overwrite the settings in /etc/idmap.conf.

CIFS
root=cifs://[<username>[:<password>]@]<server−ip>:<root−dir>

mount cifs share from <server−ip>:/<root−dir>, if no server−ip is given, use dhcp next_server. if server−ip is an IPv6 address it has to be put in brackets, e.g. [2001:DB8::1]. If a username or password are not specified as part of the root, then they must be passed on the command line through cifsuser/cifspass.

Warning
Passwords specified on the kernel command line are visible for all users via the file /proc/cmdline and via dmesg or can be sniffed on the network, when using DHCP with DHCP root−path.

cifsuser=<username>

Set the cifs username, if not specified as part of the root.

cifspass=<password>

Set the cifs password, if not specified as part of the root.

iSCSI
root=iscsi:[<username>:<password>[:<reverse>:<password>]@][<servername>]:[<protocol>]:[<port>][:[<iscsi_iface_name>]:[<netdev_name>]]:[<LUN>]:<targetname>

protocol defaults to "6", LUN defaults to "0". If the "servername" field is provided by BOOTP or DHCP, then that field is used in conjunction with other associated fields to contact the boot server in the Boot stage. However, if the "servername" field is not provided, then the "targetname" field is then used in the Discovery Service stage in conjunction with other associated fields. See rfc4173 [1] .

Example.

root=iscsi:192.168.50.1::::iqn.2009−06.dracut:target0

If servername is an IPv6 address, it has to be put in brackets:

Example.

root=iscsi:[2001:DB8::1]::::iqn.2009−06.dracut:target0

root=??? netroot=iscsi:[<username>:<password>[:<reverse>:<password>]@][<servername>]:[<protocol>]:[<port>][:[<iscsi_iface_name>]:[<netdev_name>]]:[<LUN>]:<targetname> ...

multiple netroot options allow setting up multiple iscsi disks:

Example.

root=UUID=12424547
netroot=iscsi:192.168.50.1::::iqn.2009−06.dracut:target0
netroot=iscsi:192.168.50.1::::iqn.2009−06.dracut:target1

If servername is an IPv6 address, it has to be put in brackets:

Example.

netroot=iscsi:[2001:DB8::1]::::iqn.2009−06.dracut:target0

root=??? rd.iscsi.initiator=<initiator> rd.iscsi.target.name=<target name> rd.iscsi.target.ip=<target ip> rd.iscsi.target.port=<target port> rd.iscsi.target.group=<target group> rd.iscsi.username=<username> rd.iscsi.password=<password> rd.iscsi.in.username=<in username> rd.iscsi.in.password=<in password>

manually specify all iscsistart parameter (see iscsistart −−help)

root=??? netroot=iscsi rd.iscsi.firmware=1

will read the iscsi parameter from the BIOS firmware

rd.iscsi.param=<param>

<param> will be passed as "−−param <param>" to iscsistart. This parameter can be specified multiple times.

Example.

"netroot=iscsi rd.iscsi.firmware=1 rd.iscsi.param=node.session.timeo.replacement_timeout=30"

will result in

iscsistart −b −−param node.session.timeo.replacement_timeout=30

FCoE
fcoe=<edd|interface|MAC>:{dcb|nodcb}

Try to connect to a FCoE SAN through the NIC specified by <interface> or <MAC> or EDD settings. For the second argument, currently only nodcb is supported. This parameter can be specified multiple times.

Note
letters in the MAC−address must be lowercase!

NBD
root=??? netroot=nbd:<server>:<port>[:<fstype>[:<mountopts>[:<nbdopts>]]]

mount nbd share from <server>

root=dhcp with dhcp root−path=nbd:<server>:<port>[:<fstype>[:<mountopts>[:<nbdopts>]]]

root=dhcp alone directs initrd to look at the DHCP root−path where NBD options can be specified. This syntax is only usable in cases where you are directly mounting the volume as the rootfs.

DASD
rd.dasd=....

same syntax as the kernel module parameter (s390 only)

ZFCP
rd.zfcp=<zfcp adaptor device bus ID>,<WWPN>,<FCPLUN>

rd.zfcp can be specified multiple times on the kernel command line.

Example.

rd.zfcp=0.0.4000,0x5005076300C213e9,0x5022000000000000

rd.zfcp.conf=0

ignore zfcp.conf included in the initramfs

ZNET
rd.znet=<nettype>,<subchannels>,<options>

rd.znet can be specified multiple times on the kernel command line.

Example.

rd.znet=qeth,0.0.0600,0.0.0601,0.0.0602,layer2=1,portname=foo
rd.znet=ctc,0.0.0600,0.0.0601,protocol=bar

CIO_IGNORE
rd.cio_accept=<device−ids>

Remove the devices listed in <device−ids> from the default cio_ignore kernel command−line settings. <device−ids> is a list of comma−separated CCW device ids. The default for this value is taken from the /boot/zipl/active_devices.txt file.

Example.

rd.cio_accept=0.0.0180,0.0.0800,0.0.0801,0.0.0802

ZIPL
rd.zipl=<path to blockdevice>

Update the dracut commandline with the values found in the dracut−cmdline.conf file on the given device. The values are merged into the existing commandline values and the udev events are regenerated.

Example.

rd.zipl=UUID=0fb28157−99e3−4395−adef−da3f7d44835a

Plymouth Boot Splash
plymouth.enable=0

disable the plymouth bootsplash completly.

The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.
