/sbin/installkernel

/sbin/installkernel is a shell script that installs the kernel (on a Debian Linux system?)
This script is called from /usr/src/linux/arch/i386/boot/install.sh.
The script is likely to be executed as follows: 
exec "${file}" "${KERNELRELEASE}" "${KBUILD_IMAGE}" System.map "${INSTALL_PATH}"
If installed under /sbin/installkernel, it's possible to call make install from a generic kernel source tree and the image will be installed to the proper place for Debian GNU/Linux.

/sbin/installkernel is mentioned in the Linux kernel source Makefile. Is it invoked by calling make install in the Linux kernel source tree?
