That would be a silly way do it. chroot just changes the root directory,
nothing more. It only gets looked at when you use a / at the beginning of a
filename or use .. to go to the parent directory.
Normally you're just chrooted to the real /, so there is no performance
difference compared to chrooting elsewhere.
