Make sure your kernel + knows how to decompress the generated initramfs, + otherwise you will not be able to boot. + --no-compress Do not compress the generated initramfs. This will + override any other compression options. + --squash-compressor [COMPRESSION] + Specify the compressor and compressor specific options + used by mksquashfs if squash module is called when + building the initramfs. + --enhanced-cpio Attempt to reflink cpio file data using dracut-cpio. + --list-modules List all available dracut modules. + -M, --show-modules Print included module's name to standard output during + build. + --keep Keep the temporary initramfs for debugging purposes. + --printsize Print out the module install size. + --sshkey [SSHKEY] Add SSH key to initramfs (use with ssh-client module). + --logfile [FILE] Logfile to use (overrides configuration setting). + --reproducible Create reproducible images. + --no-reproducible Do not create reproducible images. + --loginstall [DIR] Log all files installed from the host to [DIR]. + --uefi Create an UEFI executable with the kernel cmdline and + kernel combined. + --no-uefi Disables UEFI mode. + --no-machineid Affects the default output filename of the UEFI + executable, discarding the <MACHINE_ID> part. + --uefi-stub [FILE] Use the UEFI stub [FILE] to create an UEFI executable. + --uefi-splash-image [FILE] + Use [FILE] as a splash image when creating an UEFI + executable.
