Is the null device accessible in a chroot with no /dev/ mounted? I'd guess not...

And I had some weird bugs once where /dev/null was not readable (a bug in the linux kernel Makefile had replaced /dev/null with a regular file owned by root and was not readable).

I know these are corner cases, but that's what the question is all about, isn't it?
