consistently on the qemu vm, with the image downloaded from cdimage.d.o. I think it can be reproduced by following snippets, ``` #include <errno.h> #include <fcntl.h> #include <stdio.h> #include <sys/stat.h> int main() { char *s = "test"; mkfifo(s, S_IRUSR | S_IWUSR); open(s, O_WRONLY | O_NONBLOCK); perror(NULL); return 0; } ``` On linux, it prints "No such device or address"; On the hurd vm, it prints "Computer bought the farm". -- Shengjing Zhu
