To be precise, the config option CONFIG_LOCALVERSION appends a string to
the end of the kernel version, which installkernel uses to place the
kernel image.
If /boot/vmlinuz exists, then it is moved to /boot/vmlinuz.old, and a
*symlink* from /boot/vmlinuz is created to "vmlinuz-${VERSION}". If
/boot/vmlinuz did *not* exist before installation, then no symlink is
created. installkernel also copies your .config to
/boot/config-${VERSION}, performing the same move and symlink operation.
In addition, if you *do* install the same kernel version twice, it will
move your old version out of the way (to vmlinuz-${VERSION}.old) first,
so even if you do forget to update your .config, you will still have
both kernels.
To see exactly what "make install" does, read /sbin/installkernel (a
/bin/sh script), as that's all `make install` calls (well, it first
checks for ~/bin/${CROSS_COMPILE}installkernel, and calls it, if it
exists, which allows you to customize the installation process).
Personally, I will set CONFIG_LOCALVERSION to ".#" or "-r0.#" on a
second+ compilation of the same kernel version. (My current kernel is
2.6.28-gentoo-r1.2).
