update-miniramfs8

Generate a miniramfs image

Usage

update-miniramfs {-c | -d | -u} [-k version]

update-miniramfs -h

Overview

The update-miniramfs script manages your miniramfs images on your local box. It keeps track of the existing miniramfs archives in /boot. There are three modes of operation create, update or delete. You must at least specify one of those modes.

The miniramfs is a gzipped cpio archive containing the absolute minimum required to find and load the real initramfs. Once this is loaded boot is handed off to the initramfs.

Options

-k version

Set the specific kernel version to generate a miniramfs for. For example the output of uname -r for your currently running kernel. This argument is mandatory for create/delete and ignored for update.

-c

This mode creates a new miniramfs archive.

-u

This mode updates all miniramfs archives and creates new ones for all newly installed kernels.

-d

This mode deletes an existing miniramfs archive.

-h, --help

Print a short help page describing the available options in update-miniramfs.

Examples

Update the miniramfs of all installed kernels (including those currently without miniramfs archives):

update-miniramfs -u

Create the miniramfs for a specific kernel:

update-miniramfs -c -k 6.0.0-6-amd64
