On IA-64, a different system call is used: int __clone2(int (*fn)(void *), void *child_stack_base, size_t stack_size, int flags, void *arg, ... /* pid_t *pid, struct user_desc *tls, pid_t *ctid */ ); The __clone2() system call operates in the same way as clone(), except that child_stack_base points to the lowest address of the child's stack area, and stack_size specifies the size of the stack pointed to by child_stack_base. The function clone() is used in /src/lxc_container.c.
