but that’s why you can’t make exercises using perl,python,C,lisp,haskell,ruby etc.etc. in a wims chroot : because they are not installed…however in servers -without the extra security of a chroot- one can try to escape to the « real system » ,when exploiting some « new_and_unknown_to_wims_security_flaw » in the aux. software needed by wims.
