  11 DESCRIPTION
  12 -----------
  13 The root device used by the kernel is specified in the boot configuration
  14 file on the kernel command line, as always.
  15
  16 The traditional _root=/dev/sda1_ style device specification is allowed, but not
  17 encouraged. The root device should better be identified by LABEL or UUID. If a
  18 label is used, as in _root=LABEL=<label_of_root>_ the initramfs will search all
  19 available devices for a filesystem with the appropriate label, and mount that
  20 device as the root filesystem. _root=UUID=<uuidnumber>_ will mount the partition
  21 with that UUID as the root filesystem.
  22
  23 In the following all kernel command line parameters, which are processed by
  24 dracut, are described.
  25
  26 "rd.*" parameters mentioned without "=" are boolean parameters. They can be
  27 turned on/off by setting them to {0|1}. If the assignment with "=" is missing
  28 "=1" is implied. For example _rd.info_ can be turned off with _rd.info=0_ or
  29 turned on with _rd.info=1_ or _rd.info_. The last value in the kernel command
  30 line is the value, which is honored.
  31
  32 Standard
  33 ~~~~~~~~
  34 **init=**_<path to real init>_::
  35     specify the path to the init programm to be started after the initramfs has
  36     finished
  37
  38 **root=**_<path to blockdevice>_::
  39     specify the block device to use as the root filesystem.

  55 ----
  56 rootfstype=ext3
  57 ----
  58
  59 **rootflags=**_<mount options>_::
  60     specify additional mount options for the root filesystem. If not set,
  61     _/etc/fstab_ of the real root will be parsed for special mount options and
  62     mounted accordingly.
  63
  64 **ro**::
  65     force mounting _/_ and _/usr_ (if it is a separate device) read-only.  If
  66     none of ro and rw is present, both are mounted according to _/etc/fstab_.
  67
  68 **rw**::
  69     force mounting _/_ and _/usr_ (if it is a separate device) read-write.
  70     See also ro option.
  71
  72 **rd.fstab=0**::
  73     do not honor special mount options for the root filesystem found in
  74     _/etc/fstab_ of the real root.
  75
  76 **resume=**_<path to resume partition>_::
  77     resume from a swap partition
  78 +
  79 E.g.:

  85 ----
  86
  87 **rd.skipfsck**::
  88     skip fsck for rootfs and _/usr_.  If you're mounting _/usr_ read-only and
  89     the init system performs fsck before remount, you might want to use this
  90     option to avoid duplication.

 200     disable crypto LUKS detection
 201
 202 **rd.luks.uuid=**_<luks uuid>_::
 203     only activate the LUKS partitions with the given UUID. Any "luks-" of the
 204     LUKS UUID is removed before comparing to _<luks uuid>_.
 205     The comparisons also matches, if _<luks uuid>_ is only the beginning of the
 206     LUKS UUID, so you don't have to specify the full UUID.
 207     This parameter can be specified multiple times.
 208
 209 **rd.luks.allow-discards=**_<luks uuid>_::
 210     Allow  using  of discards (TRIM) requests for LUKS partitions with the given UUID.
 211     Any "luks-" of the LUKS UUID is removed before comparing to _<luks uuid>_.

 222 crypto LUKS - key on removable device support
 223 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 224 **rd.luks.key=**_<keypath>:<keydev>:<luksdev>_::
 225     _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.
 226 +
 227 _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.
 228 +
 229 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:
 230 +
 231 ----
 232 rd.luks.key=/foo/bar.key

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

 302 =====================
 303 dhcp|on|any|dhcp6::: get ip from dhcp server on a specific interface
 304 auto6::: do IPv6 autoconfiguration
 305 <macaddr>::: optionally **set** <macaddr> on the <interface>. This
 306 cannot be used in conjunction with the **ifname** argument for the
 307 same <interface>.
 308 =====================
 309
 310 [IMPORTANT]
 311 =====================
 312 It is recommended to either bind <interface> to a MAC with the **ifname**
 313 argument. Or use biosdevname to name your interfaces, which will then have names according to their hardware location.

 320     explicit network configuration. If you want do define a IPv6 address, put it
 321     in brackets (e.g. [2001:DB8::1]). This parameter can be specified multiple
 322     times.
 323 +

 340     Assign network device name <interface> (ie "bootnet") to the NIC with MAC <MAC>.
 341 +
 342 [IMPORTANT]
 343
 344 Do **not** use the default kernel naming scheme for the interface name,
 345 as it can conflict with the kernel names. So, don't use "eth[0-9]+" for the
 346 interface name. Better name it "bootnet" or "bluesocket".
 347
 348 **bootdev=**_<interface>_::
 349     specify network interface to use routing and netroot information from.
 350     Required if multiple ip= lines are used.
 351
 352 **nameserver=**__<IP>__ [**nameserver=**__<IP>__ ...]::
 353     specify nameserver(s) to use
 354

 357
 358 **vlan=_<vlanname>_:_<phydevice>_**::
 359     Setup vlan device named <vlanname> on <phydeivce>.
 360     We support the four styles of vlan names: VLAN_PLUS_VID (vlan0005), VLAN_PLUS_VID_NO_PAD (vlan5),
 361     DEV_PLUS_VID (eth0.0005), DEV_PLUS_VID_NO_PAD (eth0.5)
 362
 363 **bond=_<bondname>_[:_<bondslaves>_:[:_<options>_]]**::
 364     Setup bonding device <bondname> on top of <bondslaves>.
 365     <bondslaves> is a comma-separated list of physical (ethernet) interfaces.
 366     <options> is a comma-separated list on bonding options (modinfo bonding for details)
 367     in format compatible with initscripts. If <options> includes multi-valued arp_ip_target option,
 368     then its values should be separated by semicolon.
 369     Bond without parameters assumes bond=bond0:eth0,eth1:mode=balance-rr
 370
 371 **bridge=_<bridgename>_:_<ethnames>_**::
 372     Setup bridge <bridgename> with <ethnames>. <ethnames> is a comma-separated
 373     list of physical (ethernet) interfaces. Bridge without parameters assumes bridge=br0:eth0

 378 **root=**[_<server-ip>_:]_<root-dir>_[:_<nfs-options>_]::
 379     mount nfs share from <server-ip>:/<root-dir>, if no server-ip is given, use
 380     dhcp next_server. if server-ip is an IPv6 address it has to be put in

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

 462     Try to connect to a FCoE SAN through the NIC specified by _<interface>_ or
 463     _<MAC>_ or EDD settings. For the second argument, currently only nodcb is
 464     supported. This parameter can be specified multiple times.
 465 +
 466 [NOTE]
 467 letters in the MAC-address must be lowercase!

 469 NBD
 470 ~~~
 471 **root=**??? **netroot=**nbd:_<server>_:_<port>_[:_<fstype>_[:_<mountopts>_[:_<nbdopts>_]]]::
 472     mount nbd share from <server>
 473
 474 **root=dhcp** with **dhcp** **root-path=**nbd:_<server>_:_<port>_[:_<fstype>_[:_<mountopts>_[:_<nbdopts>_]]]::
 475     root=dhcp alone directs initrd to look at the DHCP root-path where NBD
 476     options can be specified. This syntax is only usable in cases where you are
 477     directly mounting the volume as the rootfs.
