Say, there are multiple /sbin/modprobe

/sbin/modprobe
/var/chroot/sbin/modprobe

and only /var/chroot/sbin/modprobe needs request_module() whereas
/sbin/modprobe does not need request_module(). Why do we need to make
execl("/sbin/modprobe", "--help", NULL) from chroot("/var/chroot/") fail
by denying request_module() that does not cause recursion?
