When trying to use the new, recommended ini-style config:

```
pkg install rabbitmq
pkg install erlang-cuttlefish
cd /usr/local/etc/rabbitmq
rm rabbitmq.config
fetch https://raw.githubusercontent.com/rabbitmq/rabbitmq-server/v3.7.x/docs/rabbitmq.conf.example
mv rabbitmq.conf.example rabbitmq.conf

whereis cuttlefish
cuttlefish: /usr/local/sbin/cuttlefish

rabbitmq-server

BOOT FAILED

Crash dump is being written to: /var/log/rabbitmq/erl_crash.dump...
```

However, symlinking to /usr/local/sbin/cuttlefish allows the server to start, but surely there's a better way?

```
ln -s /usr/local/bin/cuttlefish /usr/local/sbin/cuttlefish
