39 Usage: $0 [OPTION]... <initramfs> <kernel-version>
41 Version: $DRACUT_VERSION
43 Creates initial ramdisk images for preloading modules
45 -f, --force Overwrite existing initramfs file.
46 -m, --modules [LIST] Specify a space-separated list of dracut modules to
47 call when building the initramfs. Modules are located
48 in /usr/lib/dracut/modules.d.
49 -o, --omit [LIST] Omit a space-separated list of dracut modules.
50 -a, --add [LIST] Add a space-separated list of dracut modules.
51 -d, --drivers [LIST] Specify a space-separated list of kernel modules to
52 exclusively include in the initramfs.
53 --add-drivers [LIST] Specify a space-separated list of kernel
54 modules to add to the initramfs.
55 --omit-drivers [LIST] Specify a space-separated list of kernel
56 modules not to add to the initramfs.
57 --filesystems [LIST] Specify a space-separated list of kernel filesystem
58 modules to exclusively include in the generic
60 -k, --kmoddir [DIR] Specify the directory, where to look for kernel
62 --fwdir [DIR] Specify additional directories, where to look for
63 firmwares, separated by :
64 --kernel-only Only install kernel drivers and firmware files
65 --no-kernel Do not install kernel drivers and firmware files
66 --strip Strip binaries in the initramfs
67 --nostrip Do not strip binaries in the initramfs (default)
68 --prefix [DIR] Prefix initramfs files with [DIR]
69 --noprefix Do not prefix initramfs files (default)
70 --mdadmconf Include local /etc/mdadm.conf
71 --nomdadmconf Do not include local /etc/mdadm.conf
72 --lvmconf Include local /etc/lvm/lvm.conf
73 --nolvmconf Do not include local /etc/lvm/lvm.conf
74 --fscks [LIST] Add a space-separated list of fsck helpers.
75 --nofscks Inhibit installation of any fsck helpers.
76 -h, --help This message
77 --debug Output debug information of the build process
78 --profile Output profile information of the build process
79 -L, --stdlog [0-6] Specify logging level (to standard error)
80 0 - suppress any messages
85 5 - debug info (here starts lots of output)
86 6 - trace info (and even more)
87 -v, --verbose Increase verbosity level (default is info(4))
88 -q, --quiet Decrease verbosity level (default is info(4))
89 -c, --conf [FILE] Specify configuration file to use.
90 Default: /etc/dracut.conf
91 --confdir [DIR] Specify configuration directory to use *.conf files
92 from. Default: /etc/dracut.conf.d
93 --tmpdir [DIR] Temporary directory to be used instead of default
95 -l, --local Local mode. Use modules from the current working
96 directory instead of the system-wide installed in
97 /usr/lib/dracut/modules.d.
98 Useful when running dracut from a git checkout.
99 -H, --hostonly Host-Only mode: Install only what is needed for
100 booting the local host instead of a generic host.
101 --no-hostonly Disables Host-Only mode
102 --fstab Use /etc/fstab to determine the root device.
103 --add-fstab [FILE] Add file to the initramfs fstab
104 --mount "[DEV] [MP] [FSTYPE] [FSOPTS]"
105 Mount device [DEV] on mountpoint [MP] with filesystem
106 [FSTYPE] and options [FSOPTS] in the initramfs
107 -i, --include [SOURCE] [TARGET]
108 Include the files in the SOURCE directory into the
109 Target directory in the final initramfs.
110 If SOURCE is a file, it will be installed to TARGET
111 in the final initramfs.
112 -I, --install [LIST] Install the space separated list of files into the
114 --gzip Compress the generated initramfs using gzip.
115 This will be done by default, unless another
116 compression option or --no-compress is passed.
117 --bzip2 Compress the generated initramfs using bzip2.
118 Make sure your kernel has bzip2 decompression support
119 compiled in, otherwise you will not be able to boot.
120 --lzma Compress the generated initramfs using lzma.
121 Make sure your kernel has lzma support compiled in,
122 otherwise you will not be able to boot.
123 --xz Compress the generated initramfs using xz.
124 Make sure that your kernel has xz support compiled
125 in, otherwise you will not be able to boot.
126 --compress [COMPRESSION] Compress the generated initramfs with the
127 passed compression program. Make sure your kernel
128 knows how to decompress the generated initramfs,
129 otherwise you will not be able to boot.
130 --no-compress Do not compress the generated initramfs. This will
131 override any other compression options.
132 --list-modules List all available dracut modules.
133 -M, --show-modules Print included module's name to standard output during
135 --keep Keep the temporary initramfs for debugging purposes
136 --printsize Print out the module install size
137 --sshkey [SSHKEY] Add ssh key to initramfs (use with ssh-client module)
139 If [LIST] has multiple arguments, then you have to put these in quotes.
