NAME

make-initrd - creates initial ramdisk images for preloading modules

SYNOPSIS

make-initrd []++ make-initrd guess-modules [|]++ make-initrd guess-config++ make-initrd bug-report

DESCRIPTION

make-initrd is a new, uevent-driven initramfs infrastructure based around udev. Without options, the program generates images for all the configuration files.

bug-report

Makes the archive for developers when bug happens. The archive contains
information about disks and partitions and other information about
hardware. It does not contain information about users.

guess-config

Guesses the current configuration and generates the config file.

guess-modules [|]

Shows kernel module needed to mount specified mountpoint or block device.

feature-info [name [name1...]]

Shows information about feature. Example:

```
$ make-initrd feature-info mdadm luks

Feature mdadm
  requires : add-udev-rules
  disables : raid
  required : guestfs kickstart

Feature luks
  requires : depmod-image devmapper modules-crypto-user-api system-glibc
  disables :
  required : guestfs kickstart
```

uki Creates an UEFI executable with the kernel, cmdline and initramfs combined.

OPTIONS

--latest-kernel create an initramfs image for the highest kernel version that can be found, cnot the currently running kernel.

-D, --no-depmod don’t recreate a list of module dependencies.

-N, --no-checks don’t check /dev, /proc and the kernel modules directory.

-c, --config=FILE set custom config file.

-b, --bootdir=DIR set boot directory (default: /boot).

-k, --kernel=VERSION set kernel version (default: currently running kernel).

-v, --verbose print a message for each action. The option can be specified more than once. Each time the option is specified, the detail of the messages increases.

-V, --version Show version of program and exit.

-h, --help Show this text and exit.

ENVIRONMENT

INITRD_WORKDIR - Sets working directory (default: /tmp or $TMPDIR if set).

BLACKLIST_MODULES - List of modules that need to be ignored.

SYSFS_PATH - Sets sysfs placement.

FILES

/etc/initrd.mk - Main configuration file for make-initrd.
