It's not lilo who creates the content of /proc/cmdline but Linux
itself. Lilo just passes on some parameters to Linux, which Linux
(happily) recognizes as such. On the other hand, you can pass any
parameter to Linux, even ones which doesn't exist. In this case, Linux
just ignores them while still putting them in /proc/cmdline. You could
use this feature to differentiate your kernels. For example, you could
add a parameter "kernel_image=<image>" to the "kernel" grub command.
