9 dracut.cmdline - dracut kernel command line options
13 The root device used by the kernel is specified in the boot configuration
14 file on the kernel command line, as always.
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.
23 In the following all kernel command line parameters, which are processed by
24 dracut, are described.
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.
34 **init=**_<path to real init>_::
35 specify the path to the init programm to be started after the initramfs has
38 **root=**_<path to blockdevice>_::
39 specify the block device to use as the root filesystem.
45 root=/dev/disk/by-path/pci-0000:00:1f.1-scsi-0:0:1:0-part1
46 root=/dev/disk/by-label/Root
48 root=/dev/disk/by-uuid/3f5ad593-4546-4a94-a374-bcfb68aa11f7
49 root=UUID=3f5ad593-4546-4a94-a374-bcfb68aa11f7
50 root=PARTUUID=3f5ad593-4546-4a94-a374-bcfb68aa11f7
53 **rootfstype=**_<filesystem type>_:: "auto" if not specified, e.g.:
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
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_.
69 force mounting _/_ and _/usr_ (if it is a separate device) read-write.
72 **rd.auto** **rd.auto=1**::
73 enable autoassembly of special devices like cryptoLUKS, dmraid, mdraid or lvm.
74 Default is off as of dracut version >= 024.
77 do not honor special mount options for the root filesystem found in
78 _/etc/fstab_ of the real root.
80 **resume=**_<path to resume partition>_::
81 resume from a swap partition
86 resume=/dev/disk/by-path/pci-0000:00:1f.1-scsi-0:0:1:0-part1
87 resume=/dev/disk/by-uuid/3f5ad593-4546-4a94-a374-bcfb68aa11f7
88 resume=UUID=3f5ad593-4546-4a94-a374-bcfb68aa11f7
92 skip fsck for rootfs and _/usr_. If you're mounting _/usr_ read-only and
93 the init system performs fsck before remount, you might want to use this
94 option to avoid duplication.
99 **rd.driver.blacklist=**_<drivername>[,<drivername>,...]_::
100 do not load kernel module <drivername>. This parameter can be specified
103 **rd.driver.pre=**_<drivername>[,<drivername>,...]_::
104 force loading kernel module <drivername>. This parameter can be specified
107 **rd.driver.post=**_<drivername>[,<drivername>,...]_::
108 force loading kernel module <drivername> after all automatic loading modules
109 have been loaded. This parameter can be specified multiple times.
111 **rd.retry=**_<seconds>_::
112 specify how long dracut should wait for devices to appear.
113 The default is 30 seconds. After 2/3 of the time, degraded raids are force
114 started. If you have hardware, which takes a very long time to announce its
115 drives, you might want to extend this value.
118 accept self-signed certificates for ssl downloads.
120 **rd.ctty=**_<terminal device>_**::
121 specify the controlling terminal for the console.
122 This is useful, if you have multiple "console=" arguments.
124 [[dracutkerneldebug]]
127 If you are dropped to an emergency shell, the file _/run/initramfs/rdsosreport.txt_ is created,
128 which can be safed to a (to be mounted by hand) partition (usually /boot) or a USB stick.
129 Additional debugging info can be produced by adding **rd.debug** to the kernel command line.
130 _/run/initramfs/rdsosreport.txt_ contains all logs and the output of some tools.
131 It should be attached to any report about dracut problems.
134 print informational output though "quiet" is set
137 allow dropping to a shell, if root mounting fails
140 set -x for the dracut shell.
141 If systemd is active in the initramfs, all output is logged to the systemd journal,
142 which you can inspect with "journalctl -ab".
143 If systemd is not active, the logs are written to dmesg and _/run/initramfs/init.log_.
144 If "quiet" is set, it also logs to the console.
146 **rd.memdebug=[0-3]**::
147 Print memory usage info at various points, set the verbose level from 0 to 3
148 Higher level means more debugging output:
150 1 - partial /proc/meminfo
152 3 - /proc/meminfo + /proc/slabinfo
155 drop to a shell at the end
157 **rd.break=**_{cmdline|pre-udev|pre-trigger|initqueue|pre-mount|mount|pre-pivot|cleanup}_::

176 **vconsole.keymap.ext=**_<list of keymap base file names>_::
177 list of extra keymaps to bo loaded (sep. by space); will be written as
178 EXT_KEYMAP to _/etc/vconsole.conf_ in the initramfs

192 **vconsole.font.map=**_<console map base file name>_::
193 see description of '-m' parameter in setfont manual; taken from consoletrans
194 directory; will be written as FONT_MAP to _/etc/vconsole.conf_ in the
197 **vconsole.font.unimap=**_<unicode table base file name>_::
198 see description of '-u' parameter in setfont manual; taken from unimaps
199 directory; will be written as FONT_UNIMAP to _/etc/vconsole.conf_ in the

204 basis of LANG value (whether it ends with ".utf8" (or similar) or not); will
205 be written as LANG to _/etc/locale.conf_ in the initramfs; e.g.:
208 locale.LANG=pl_PL.utf8
211 **locale.LC_ALL=**_<locale>_::
212 taken from the environment; will be written as LC_ALL to _/etc/locale.conf_
218 disable LVM detection
220 **rd.lvm.vg=**_<volume group name>_::

225 only activate the logical volumes with the given name. rd.lvm.lv can be
226 specified multiple times on the kernel command line.
229 remove any _/etc/lvm/lvm.conf_, which may exist in the initramfs
234 disable crypto LUKS detection
236 **rd.luks.uuid=**_<luks uuid>_::
237 only activate the LUKS partitions with the given UUID. Any "luks-" of the
238 LUKS UUID is removed before comparing to _<luks uuid>_.
239 The comparisons also matches, if _<luks uuid>_ is only the beginning of the
240 LUKS UUID, so you don't have to specify the full UUID.
241 This parameter can be specified multiple times.
243 **rd.luks.allow-discards=**_<luks uuid>_::
244 Allow using of discards (TRIM) requests for LUKS partitions with the given UUID.
245 Any "luks-" of the LUKS UUID is removed before comparing to _<luks uuid>_.
246 The comparisons also matches, if _<luks uuid>_ is only the beginning of the
247 LUKS UUID, so you don't have to specify the full UUID.
248 This parameter can be specified multiple times.
250 **rd.luks.allow-discards**::
251 Allow using of discards (TRIM) requests on all LUKS partitions.
253 **rd.luks.crypttab=0**::
254 do not check, if LUKS partition is in _/etc/crypttab_
256 crypto LUKS - key on removable device support
257 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
258 **rd.luks.key=**_<keypath>:<keydev>:<luksdev>_::
259 _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.
261 _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.
263 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:
266 rd.luks.key=/foo/bar.key
269 As you see, you can skip colons in such a case.
272 ===============================
273 dracut pipes key to cryptsetup with _-d -_ argument, therefore you need to pipe
274 to crypsetup luksFormat with _-d -_, too!
276 Here follows example for key encrypted with GPG:
279 gpg --quiet --decrypt rootkey.gpg \
280 | cryptsetup -d - -v \
281 --cipher serpent-cbc-essiv:sha256 \
282 --key-size 256 luksFormat /dev/sda3
285 If you use plain keys, just add path to _-d_ option:
288 cryptsetup -d rootkey.key -v \
289 --cipher serpent-cbc-essiv:sha256 \
290 --key-size 256 luksFormat /dev/sda3

397 Assign network device name <interface> (ie "bootnet") to the NIC with MAC <MAC>.
401 Do **not** use the default kernel naming scheme for the interface name,
402 as it can conflict with the kernel names. So, don't use "eth[0-9]+" for the
403 interface name. Better name it "bootnet" or "bluesocket".
405 **bootdev=**_<interface>_::
406 specify network interface to use routing and netroot information from.

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

493 protocol defaults to "6", LUN defaults to "0". If the "servername" field is
494 provided by BOOTP or DHCP, then that field is used in conjunction with other
495 associated fields to contact the boot server in the Boot stage. However, if
496 the "servername" field is not provided, then the "targetname" field is then
497 used in the Discovery Service stage in conjunction with other associated
