For the moment I just use the chcontext command to get rid of filesystem
part. But even if the tested filesystem is not the host filesystem, I
just keep in mind that all applications running inside a 'guest' will
use _this_ filesystem and not the host one.

of different 'virtualisation' layers (chcontext + ipv4root + chroot).
But it's not the case for all solutions.
