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.
