Yes, something must be going wrong. I wrote the following small
program:
#define _GNU_SOURCE
#include <stdio.h>
#include <errno.h>
#include <error.h>
#include <hurd.h>
#include <fcntl.h>
#include <hurd/fs.h>
int main (int argc, char *argv[])
{
file_t file;
error_t err;
if (argc != 2)
error (1, 0, "Usage: %s file", argv[0]);
file = file_name_lookup (argv[1], O_READ, 0);
if (file == MACH_PORT_NULL)
error (1, errno, "Looking up %s", argv[1]);
printf ("Got a port to `%s'.\n", argv[1]);
err = dir_mkdir (file, "boohbah", 0);
if (err)
error (1, err, "Making boohbah");
return 0;
}
Here are the results:

Seems to work fairly well in this scenario.
