37 Usage: $0 [OPTION]... <initramfs> <kernel-version>
39 Version: $DRACUT_VERSION
41 Creates initial ramdisk images for preloading modules
43 -f, --force Overwrite existing initramfs file.
44 -m, --modules [LIST] Specify a space-separated list of dracut modules to
45 call when building the initramfs. Modules are located
46 in /usr/lib/dracut/modules.d.
47 -o, --omit [LIST] Omit a space-separated list of dracut modules.
48 -a, --add [LIST] Add a space-separated list of dracut modules.
49 -d, --drivers [LIST] Specify a space-separated list of kernel modules to
50 exclusively include in the initramfs.
51 --add-drivers [LIST] Specify a space-separated list of kernel
52 modules to add to the initramfs.
53 --omit-drivers [LIST] Specify a space-separated list of kernel
54 modules not to add to the initramfs.
55 --filesystems [LIST] Specify a space-separated list of kernel filesystem
56 modules to exclusively include in the generic
58 -k, --kmoddir [DIR] Specify the directory, where to look for kernel
60 --fwdir [DIR] Specify additional directories, where to look for
61 firmwares, separated by :
62 --kernel-only Only install kernel drivers and firmware files
63 --no-kernel Do not install kernel drivers and firmware files
64 --strip Strip binaries in the initramfs
65 --nostrip Do not strip binaries in the initramfs (default)
66 --prefix [DIR] Prefix initramfs files with [DIR]
67 --noprefix Do not prefix initramfs files (default)
68 --mdadmconf Include local /etc/mdadm.conf
69 --nomdadmconf Do not include local /etc/mdadm.conf
70 --lvmconf Include local /etc/lvm/lvm.conf
71 --nolvmconf Do not include local /etc/lvm/lvm.conf
72 --fscks [LIST] Add a space-separated list of fsck helpers.
73 --nofscks Inhibit installation of any fsck helpers.
74 -h, --help This message
75 --debug Output debug information of the build process
76 --profile Output profile information of the build process
77 -L, --stdlog [0-6] Specify logging level (to standard error)
78 0 - suppress any messages
83 5 - debug info (here starts lots of output)
84 6 - trace info (and even more)
85 -v, --verbose Increase verbosity level (default is info(4))
86 -q, --quiet Decrease verbosity level (default is info(4))
87 -c, --conf [FILE] Specify configuration file to use.
88 Default: /etc/dracut.conf
89 --confdir [DIR] Specify configuration directory to use *.conf files
90 from. Default: /etc/dracut.conf.d
91 --tmpdir [DIR] Temporary directory to be used instead of default
93 -l, --local Local mode. Use modules from the current working
94 directory instead of the system-wide installed in
95 /usr/lib/dracut/modules.d.
96 Useful when running dracut from a git checkout.
97 -H, --hostonly Host-Only mode: Install only what is needed for
98 booting the local host instead of a generic host.
99 --no-hostonly Disables Host-Only mode
100 --fstab Use /etc/fstab to determine the root device.
101 --add-fstab [FILE] Add file to the initramfs fstab
102 --mount "[DEV] [MP] [FSTYPE] [FSOPTS]"
103 Mount device [DEV] on mountpoint [MP] with filesystem
104 [FSTYPE] and options [FSOPTS] in the initramfs
105 -i, --include [SOURCE] [TARGET]
106 Include the files in the SOURCE directory into the
107 Target directory in the final initramfs.
108 If SOURCE is a file, it will be installed to TARGET
109 in the final initramfs.
110 -I, --install [LIST] Install the space separated list of files into the
112 --gzip Compress the generated initramfs using gzip.
113 This will be done by default, unless another
114 compression option or --no-compress is passed.
115 --bzip2 Compress the generated initramfs using bzip2.
116 Make sure your kernel has bzip2 decompression support
117 compiled in, otherwise you will not be able to boot.
118 --lzma Compress the generated initramfs using lzma.
119 Make sure your kernel has lzma support compiled in,
120 otherwise you will not be able to boot.
121 --xz Compress the generated initramfs using xz.
122 Make sure that your kernel has xz support compiled
123 in, otherwise you will not be able to boot.
124 --compress [COMPRESSION] Compress the generated initramfs with the
125 passed compression program. Make sure your kernel
126 knows how to decompress the generated initramfs,
127 otherwise you will not be able to boot.
128 --no-compress Do not compress the generated initramfs. This will
129 override any other compression options.
130 --list-modules List all available dracut modules.
131 -M, --show-modules Print included module's name to standard output during
133 --keep Keep the temporary initramfs for debugging purposes
134 --printsize Print out the module install size
135 --sshkey [SSHKEY] Add ssh key to initramfs (use with ssh-client module)
137 If [LIST] has multiple arguments, then you have to put these in quotes.
