Re: [PATCH] Linux I2O devices

[Robert Millan]

I overlooked that biosdisk.c seems to be doing more specific checks on the
pathname now.

  if (have_devfs () && strcmp (real_dev + len - 5, "/disc") == 0)
    {
      p = real_dev + len - 4;
      format = "part%d";
    }
  else if ((strncmp (real_dev + 5, "hd", 2) == 0
            || strncmp (real_dev + 5, "sd", 2) == 0)
           && real_dev[7] >= 'a' && real_dev[7] <= 'z')
    {
      p = real_dev + 8;
      format = "%d";
    }
  else if (strncmp (real_dev + 5, "rd/c", 4) == 0)
    {
      p = strchr (real_dev + 9, 'd');
      if (! p)
        return 0;

      p++;
      while (*p && isdigit (*p))
        p++;

      format = "p%d";
    }
  else
    {
      free (real_dev);
      return 0;
    }

For I2O we have /dev/i2o/hd[a-z][0-9].  There's also a big family of device
sets using this scheme (/dev/*/hd[a-z][0-9]).  Unless the second "if" can be
made the default option, we'll have to add knowledge of every of these device
paths here?

My spam trap is address@hidden  Note: this address is only intended for
