Interesting. First of all, know that if it's the bug I mentioned above, then this is a non-fatal error so your program should work. Nevertheless, you may be curious to find out what's going on. Let's see what filesystems you have mounted and what the mount options are. Can you post the output of the following commands?
Also, there is a space between the \ and /tmp, but it doesn't look like you entered it that way. Another way to run that command isCode:cat /etc/fstabCode:grep " /tmp" /etc/mtab
