Nope, this is really more of anomaly. The original spec had:
```
/usr/local/otm/static
/usr/local/otm/opentreemap
/usr/local/otm/env
```

But then it turns out there are some... issues.. with virtualbox shared folders. So they were moved.
I think the best layout would be:
```
/usr/local/otm/static
/usr/local/otm/app ---> shared to host machine 
/usr/local/otm/env
```
