update-miniramfs - generate a miniramfs image

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

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.

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.

This mode creates a new miniramfs archive.

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

This mode deletes an existing miniramfs archive.

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

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
