Is there a way to prevent a user from "emulating" a login screen (especially for the console)?
If you enable the magic sysrq key, you can press Alt+SysRq+k to kill all processes running on the current console. Init will then start another instance of getty, and you can log in relatively safely. The sysrq key does other stuff too, which could be a problem (like the ability for anybody to crash the box in passing) -- you may want to hack the kernel sources. &:-)
