## NAME
       installkernel - install a new kernel image

## SYNOPSIS
       **installkernel** _version_ _zImage_ _System.map_ _[directory]_

## DESCRIPTION
       **installkernel**  installs a new kernel image onto the system from the Linux source tree.  It is
       called by the Linux kernel makefiles when **make** **install** is invoked there.

       The new kernel is installed into _{directory}/vmlinuz-{version}_.  If a symbolic  link  _{direc__‐
       _tory}/vmlinuz_  already  exists,  it is refreshed by making a link from _{directory}/vmlinuz_ to
       the new kernel, and the previously installed kernel is available as _{directory}/vmlinuz.old_.

## BUGS
       **installkernel** resides in /sbin only because the Linux kernel makefiles call  it  from  there.
       It should really be in /usr/sbin.  It isn't needed to boot a system.
