Friend, you need to look up devpts. It normally goes there, for handling pty
or pseudo-terminal devices.

The root file system *IS* mounted on /. A lot of embedded devices have a
little static, read-only / partition, which provides editable access to a RAM
based file-system on top of it via all sorts of cute tricks.

Try booting with an Ubuntu live CD and see what you get, for comparison.
