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 most file system, all 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.

	COMPRESS
	      Specifies	 the  compression method used for the initramfs image.
	      mkinitramfs will default to gzip if  the	kernel	lacks  support
	      (CONFIG_RD)  or  the  corresponding  userspace  utility  is  not
	      present.

	UMASK Set the umask value of the generated initramfs file.  Useful  to
	      not disclose eventual keys.

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.
