add --mount-binfmt[=<dir>] to mount binfmt_misc filesystem, this results in clearing inherited interpreters from the previous namespace Signed-off-by: Laurent Vivier <laurent@vivier.eu>
add -l, --load-interp <file> to load a binfmt_misc interpreter at startup. The interpreter is loaded from the initial fileystem if the 'F' flags is provided, otherwise from inside the new namespace This makes possible to start a chroot of another architecture without being root.
