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
