I've configured `tmp` in `/etc/fstab` like this:

```
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 2

```

The problem is that now `/tmp` is limited to half of the machine's memory, and when it reaches that limit I'm getting "no space left on device" error.

I'd like to make it "unlimited", i.e. grow to the size of the disk.
