The su command appears to be working properly. The problem shown
above is that your system is missing the /dev/tty device node.
Something has apparently removed it! You can confirm this by running
the following.
ls -ld /dev/tty
You could repair your system by creating that device node. See the
'mknod' documentation for how.
