What does make sense is an unshare() syscall that takes the CLONE_* argument and unshares those in the current process from the parent without creating a new process. Then you can easily reproduce another namespace by value instead of by reference. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
