(now that this is merged...)
Isn't this going in the wrong direction, or am I just
mis-interpreting SUSv3?
Compare LSB bugzilla #115:
http://bugs.linuxbase.org/show_bug.cgi?id=115
open - open a file
...
ERRORS
[ENXIO]
O_NONBLOCK is set, the named file is a FIFO, O_WRONLY is set, and
no process has the file open for reading.
[ENXIO]
The named file is a character special or block special file, and
the device associated with this special file does not exist.
(Note: ENODEV is not listed as a possible return value.)
