       installkernel - install a new kernel image


       installkernel version zImage [directory]


       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 {directory}/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.


       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.
