  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.

  44 root=/dev/sda1
  45 root=/dev/disk/by-path/pci-0000:00:1f.1-scsi-0:0:1:0-part1

  51 ----
  52
  53 **rootfstype=**_<filesystem type>_:: "auto" if not specified, e.g.:
  54 +
  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 **rd.fstab=0**::
  65     do not honor special mount options for the root filesystem found in
  66     _/etc/fstab_ of the real root.
  67
  68 **resume=**_<path to resume partition>_
  69 +
  70 E.g.:
  71 +
  72 ----
  73 resume=/dev/disk/by-path/pci-0000:00:1f.1-scsi-0:0:1:0-part1

  75 resume=UUID=3f5ad593-4546-4a94-a374-bcfb68aa11f7
  76 ----
  77
  78 **rd.skipfsck**::
  79     skip fsck for rootfs and _/usr_.  If you're mounting _/usr_ read-only and
  80     the init system performs fsck before remount, you might want to use this
  81     option to avoid duplication.
  82
  83 **rd.usrmount.ro**:
  84     force mounting _/usr_ read-only.  Use this option if your init system
  85     performs remount of _/usr_ the same as it does with rootfs.
  86

 195     disable crypto LUKS detection
 196
 197 **rd.luks.uuid=**_<luks uuid>_::
 198     only activate the LUKS partitions with the given UUID. Any "luks-" of the
 199     LUKS UUID is removed before comparing to _<luks uuid>_.
 200     The comparisons also matches, if _<luks uuid>_ is only the beginning of the
 201     LUKS UUID, so you don't have to specify the full UUID.
 202     This parameter can be specified multiple times.
 203
 204 **rd.luks.allow-discards=**_<luks uuid>_::
 205     Allow  using  of discards (TRIM) requests for LUKS partitions with the given UUID.
 206     Any "luks-" of the LUKS UUID is removed before comparing to _<luks uuid>_.
 207     The comparisons also matches, if _<luks uuid>_ is only the beginning of the
 208     LUKS UUID, so you don't have to specify the full UUID.
 209     This parameter can be specified multiple times.
 210
 211 **rd.luks.allow-discards::
 212     Allow  using  of discards (TRIM) requests on all LUKS partitions.
 213
 214 **rd.luks.crypttab=0**::

 216
 217 crypto LUKS - key on removable device support
 218 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 219 **rd.luks.key=**_<keypath>:<keydev>:<luksdev>_::
 220     _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.
 221 +
 222 _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.
 223 +
 224 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:
 225 +
 226 ----
 227 rd.luks.key=/foo/bar.key

 229 +
 230 As you see, you can skip colons in such a case.

 302     explicit network configuration. If you want do define a IPv6 address, put it
 303     in brackets (e.g. [2001:DB8::1]). This parameter can be specified multiple
 304     times.
 305 +

 307
 308 **ifname=**_<interface>_:_<MAC>_::
 309     Assign network device name <interface> (ie eth0) to the NIC with MAC <MAC>.
 310     Note: If you use this option you _must_ specify an ifname= argument for all
 311     interfaces used in ip= or fcoe= arguments. However, if the interface in
 312     ip= or fcoe= is a bridge, bonding or vlan interface, you should specify
 313     an ifname= for _each_ of its underlying interfaces. This parameter can be
 314     specified multiple times.
 315
 316 **bootdev=**_<interface>_::
 317     specify network interface to use routing and netroot information from.
 318     Required if multiple ip= lines are used.

 329     DEV_PLUS_VID (eth0.0005), DEV_PLUS_VID_NO_PAD (eth0.5)
 330
 331 **bond=_<bondname>_[:_<bondslaves>_:[:_<options>_]]**::
 332     Setup bonding device <bondname> on top of <bondslaves>.
 333     <bondslaves> is a comma-separated list of physical (ethernet) interfaces.
 334     <options> is a comma-separated list on bonding options (modinfo bonding for details)
 335     in format compatible with initscripts. If <options> includes multi-valued arp_ip_target option,
 336     then its values should be separated by semicolon.
 337     Bond without parameters assumes bond=bond0:eth0,eth1:mode=balance-rr
 338
 339 **bridge=_<bridgename>_:_<ethnames>_**::
 340     Setup bridge <bridgename> with <ethnames>. <ethnames> is a comma-separated

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

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