    cat<<EOF
    Create initial ramdisk images that contain all kernel modules
    needed in the early boot process, before the root file system
    becomes available. This usually includes SCSI and/or RAID
    modules, a file system module for the root file system, or
    a network interface driver module for dhcp.

        mkinitrd [options]

        options:
          -h               This Text.
          -k "kernel list" List of kernel images for which initrd files
                           are created. Defaults to all kernels found
               in /boot.
          -i "initrd list" List of file names for the initrd; position
                 have match to "kernel list". Defaults to all
               all kernels found in /boot.
          -m "module list" Modules to include in initrd. Defaults to the
                           INITRD_MODULES variable in /etc/sysconfig/kernel.
          -u "DomU module list" Modules to include in initrd. Defaults to
                           the DOMU_INITRD_MODULES variable in
                           /etc/sysconfig/kernel.
          -f "feature list" Features to be enabled when generating initrd.
                           Available features are:
                           iscsi, md, mpath, lvm, lvm2, evms
          -b boot_dir      Boot directory. Defaults to /boot.
          -d root_device   Root device. Defaults to the device from which
                           / is mounted. Overrides the rootdev enviroment
               variable if set.
      -s size          Add splash animation and bootscreen to initrd.
      -t tmp_dir       Temporary directory. Defaults to /var/tmp.
      -D interface     Run dhcp on the specified interface.
      -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.
          -e               Use static binaries where possible (currently unavailable)
          -P               Include modules for IDE devices on the PCI bus
      -V script        Vendor specific script to run in linuxrc.
      -M map           System.map file to use.
