MKINITRD(8)							      dracut							       MKINITRD(8)

NAME
mkinitrd - is a compat wrapper, which calls dracut to generate an initramfs SYNOPSIS
mkinitrd [OPTION...] [<initrd-image>] <kernel-version> DESCRIPTION
mkinitrd creates an initramfs image <initrd-image> for the kernel with version <kernel-version> by calling "dracut". Important If a more fine grained control over the resulting image is needed, "dracut" should be called directly. OPTIONS
--version print info about the version -v, --verbose increase verbosity level -f, --force overwrite existing initramfs file. *--image-version append the kernel version to the target image <initrd-image>-<kernel-version>. --with=<module> add the kernel module <module> to the initramfs. --preload=<module> preload the kernel module <module> in the initramfs before any other kernel modules are loaded. This can be used to ensure a certain device naming, which should in theory be avoided and the use of symbolic links in /dev is encouraged. --nocompress do not compress the resulting image. --help print a help message and exit. AVAILABILITY
The mkinitrd command is part of the dracut package and is available from https://dracut.wiki.kernel.org AUTHORS
