Yes. I believe lilo passes something like a "BOOT_IMAGE=" parameter to
the kernel when it boots. The value that gets passed is the label
name of the running kernel in /etc/lilo.conf.
If you make the labels the same as an extension to the System.map file,
you can easily pull this from /proc/cmdline, and insert the relevent
link at run time.
