Comment:
@mobinmob the issue here is that we'd be changing the service behavior on an update, and it's possible someone might miss it and get locked out after a reboot. Documenting that the default service allows root login might be the safest way forward (though I'd suggest keeping it disabled in your own services). 

Does dropbear work fine if you specify `-F` twice, as well? Otherwise someone with a `conf` file might have issues.
