INITRAMFS.CONF(5)            initramfs.conf manual           INITRAMFS.CONF(5)



NAME
       initramfs.conf - configuration file for mkinitramfs


DESCRIPTION
       The behaviour of mkinitramfs can be modified by its configuration file.

       Each line in the file can be a configuration variable, a blank line, or
       a comment. The value of an variable is assigned by an statement of  the
       form: name=[value]

       Configuration options can be broken out into configuration snippets and
       placed in individual files in  the  /etc/mkinitramfs/conf.d  directory.
       Files  in  this  directory are always read after the main configuration
       file, so you can override the settings in the main config file  without
       editing it directly.


GENERAL VARIABLES
        MODULES
              Specifies the modules for the initramfs image.  The default set-
              ting is most.

              most adds all the framebuffer, acpi,  file  system,  ide,  sata,
              scsi and usb drivers.

              dep  tries  to guess which modules are necessary for the running
              box.

              netboot adds the base modules, network modules, but skips  block
              devices.

              list  includes  only modules from the additional modules list to
              load them early.


        BUSYBOX
              Include busybox utilities for the boot scripts.  If set  to  'n'
              mkinitramfs  will  build  an  initramfs without busybox.  Beware
              that many boot scripts need busybox utilities.


        KEYMAP
              If set to 'y', the console keymap  will  be  loaded  during  the
              initramfs  stage.   The  keymap  will  anyway  be  loaded by the
              initscripts later, and the packages that might need  input  will
              normally  set  this variable automatically, so there should nor-
              mally be no need to set this.


NFS VARIABLES
        BOOT  Allows to use an nfs drive  as  the  root  of  the  drive.   The
              default  is  to  boot  from local media (hard drive, USB stick).
              Set to nfs for an NFS root share.


        DEVICE
              Specifies the network interface, like eth0.


        ROOT  Allows optional root bootarg hardcoding, when  no  root  bootarg
              can be passed.  A root bootarg overrides that special setting.


        NFSROOT
              Defaults  to  auto  in  order to pick up value from DHCP server.
              Otherwise you need to specify HOST:MOUNT.
