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  {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.

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.
