The question is whether this should be merged. Indeed, the root user inside UML can bypass that anyway, if he modifies the hostfs module, compiles and loads it. So the host admin really needs to run UML in a chroot if he needs real security. What do you all think? -- Inform me of my mistakes, so I can add them to my list!
