NAME
       update-initramfs - generate an initramfs image


SYNOPSIS
       update-initramfs [-k version] [-c] [-u] [-t] [-v] [-b] [-h]

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

       The initramfs is a gzipped cpio archive.   At  boot  time,  the  kernel
       unpacks  that archive into RAM disk, mounts and uses it as initial root
       file system. All finding of the  root  device  happens  in  this  early
       userspace.


OPTIONS
        -k  version
              Set the kernel version for whom the initramfs will be generated.
              For example the output of uname -r for  your  currently  running
              kernel.


        -c    This mode creates a new initramfs.


        -u    This mode updates an existing initramfs.


        -d    This mode removes an existing initramfs.


        -t    Allows to take over an custom initramfs with a newer one.


        -v    This  option  increases  the amount of information you are given
              during the chosen action.


        -b    Set an different bootdir for the image creation.


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