Bluetooth is a security risk, therefore disabled by default

This disability can be removed in `/etc/modprobe.d/30_security-misc.conf`

```
# Blacklists bluetooth to reduce attack surface.
# Bluetooth also has a history of security vulnerabilities:

install bluetooth /bin/false
install btusb /bin/false
```

You might also need to `rfkill unblock bluetooth` also.
