Shouldn't it try to match the behaviour of the desktop version?

Well, no problem, whatever you want.

No.

The same output.
Argh. I added the following code before the continue when fd < 0:

printf("%s\n", strerror(errno));

The output then was "No such file or directory" and then I realized
that you had a typo in floppytest.c:

snprintf(path, 31, "/dev/fd%d\n", x);

That's actually bad, because there's a \n at the end of the filename.

After correcting this error, the output looks a bit better now:

O_RDONLY:

So, with O_NONBLOCK it almost immediately completes the task.
