initramfs.conf - configuration file for mkinitramfs
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
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.
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
netboot adds the base modules, network modules, but skips block
list includes only modules from the additional modules list to
load them early.
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.
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.
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.
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.
Defaults to auto in order to pick up value from DHCP server.
Otherwise you need to specify HOST:MOUNT.
