## SYNOPSIS

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

## 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.

- **-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**

- **-h**, **--help**
