That's the hard way to do the job.
First make sure udev is installed. Then add something like

The answer to OP's question of "why" it gets removed is that all /dev/ names
are temporary, and are recreated at boot time (actually at the time their
modules are inserted into the kernel) by udev, so the correct place to set
symlinks is always in udev.
