NAME
----
mkinitrd-suse - is a compat wrapper, which calls dracut to generate an initramfs

SYNOPSIS
--------
*mkinitrd* ['OPTION...']

DESCRIPTION
-----------
*mkinitrd* creates an initramfs image <initrd-image> for the kernel with
version <kernel-version> by calling *dracut*.

[IMPORTANT]
This version of mkinitrd is provided for compatibility with older
versions of mkinitrd. If a more fine grained control over the
resulting image is needed, *dracut* should be called directly.

OPTIONS
-------
**-R, --version**::
    print info about the version

**-k** _<kernel_list>_::
    List of kernel images for which initrd files are created (relative
    to _boot_dir_), Image name should begin with the following string,
    defaults to _vmlinux_ on ppc/ppc64, _image_ on s390/s390x and _vmlinuz_
    for everything else.

**-i** _<initrd_list>_::
    List of file names (relative to _boot_dir_) for the initrd; positions
    have to match the _kernel_list_. Defaults to _initrd_.

**-m** _<module_list>_::
    Modules to include in initrd, defaults to _INITRD_MODULES_ variable
    in */etc/sysconfig/kernel*.

**-f** _<feature_list>_::
    Features to be enabled for the initrd. In general mkinitrd
    configures the initrd for the root device it is started from. With
    this option additional feature can be enabled.

**-b** _<bootdir>_::
    Boot directory, defaults to */boot*, where the initrd is created.

**-d** _<root_device>_::
    Root device, defaults to the device from which the root_dir is
    mounted; overwrites the rootdev environment variable if set

**-s** _<size>_::
    Add splash animation and bootscreen to initrd.

**-D** _<interface>::
    Run dhcp on the specified interface (for example "eth0").

**-I** _<interface>::
    Configure the specified interface statically.

**-a** _<acpi_dsdt>::
    Attach compiled ACPI DSDT (Differentiated System Description Table)
    to initrd. This replaces the DSDT of the BIOS. Defaults to the
    _ACPI_DSDT_ variable in */etc/sysconfig/kernel*.

**-M** _<map>::
    System.map file to use.

**-B**::
    Don’t run the *update-bootloader(8)* script after the initrd(s) have
    been created. This is useful if you call mkinitrd(8) for anything
    else than the running system.

**-A**::
    Create a so called "monster initrd" which includes all available
    features and modules. This calls dracut with --no-hostonly and
    --no-hostonly-cmdline parameters internally, instead of the default
    --hostonly and --hostonly-cmdline.

**-v, --verbose**::
    increase verbosity level

**-L**::
    Disable logging to _/var/log/YaST2/mkinitrd.log_. This is useful for
    testing if you don’t want to clutter the system log.

**--help**::
    print a help message and exit.
