NAME¶

update-miniramfs - generate a miniramfs image

SYNOPSIS¶

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

DESCRIPTION¶

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
