Explain me bzImage, /vmlinuz to build kernel

Here is what I read from

To use a kernel, copy the and config files to your /boot directory and copy the kernel image to /vmlinuz. Run /sbin/lilo(8) to install LILO for the new kernel, and then reboot your system. That's all there is to installing a new kernel.
I try to find dir /vmlinuz in / but I can't locate it elsewhere in /. So, is it unreal dir?

As far as I know this phrase, after we copy bzImage to /vmlinuze, we run /sbin/lilo--->then we will boot into new kernel. Do you know why?

it's /boot/vmlinuz, a link to the actual kernel, for example /boot/vmlinuz-ide-2.4.26 on slackware 9.1...

the file is

You probably want to use a different name like
to avoid overwriting the old one in case the new one doesn't work. /etc/lilo.conf has to be edited accordingly.

I recommend either using a custom name as was suggested above, or copying the old one to vmlinuz-old before you replacing that and including a vmlinuz-old entry in your lilo.conf so you can boot if there are issues
