I ran that "sbt debian:packageBin" command and compared the resulting deb file to one of my own.
As far as I can tell, the only significant difference is that the sbt-generated package doesn't install a bbb-apps-akka as a system service, but if you don't know how to do that, or just don't know that it's needed, then it's a serious problem.
If you want to use the sbt-generated package, you'll probably want to pull the /lib/systemd/system/bbb-apps-akka.service file from the standard package and install it yourself, then run "sudo systemctl start bbb-apps-akka" to start it, and "sudo systemctl enable bbb-apps-akka" to run it automatically after a reboot. Also, when you remove or upgrade the package, it will not stop or disable the service, or remove the (untracked) file from /lib/systemd/system.
I'm working on a set of packaging scripts and pretty have bbb-apps-akka working. I'll follow up with another message when it's ready to go.
