There is. Don't use lilo. Have a little DOS partition. Don't include
DOS support in the kernel. Use a little DOS bootmenu to start Linux.
But default to start DOS there. This prevents from having someone
run lilo on a new kernel and do a shutdown -r.

If you are on the console, you can still reboot and choose "Linux" from
the boot menu.
