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 compability 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 enviroment 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.

AVAILABILITY

The mkinitrd command is part of the dracut package and is available from m[blue]https://dracut.wiki.kernel.orgm[]
