# Function to copy various kernel boot image products to the boot directory,
# preserve a generation of old images (just like the manual kernel build's
# "make install" does), and maintain the symlinks (if enabled).
#
# Arguments:
# $1 Symlink name. Symlink on the boot directory. Path not included.
# $2 Source image. Fully qualified path name of the source image.
# $3 Dest image. Name of the destination image in the boot directory,
# no path included. This script pushd's into ${BOOTDIR} in order to
# create relative symlinks just like the manual kernel build.
