There are two approaches to fix this issue - 1. Simple but not ideal, 2. Complex but ideal

1. Simple approach - Even though the system unit would be called dcos-net, keep the erlang node name as "navstar"
Pros: 1. smooth upgrade as old and new node would still operate on "navstar"
2. less code less risky
Cons: 1. May cause confusion because system unit name would be different from erlang node name
2. Not ideal due to above reason

2. Complex approach - Change the erlang node name to "dcos-net"
Pros: 1. Clean solution as systemd unit name corresponds to erlang node name
2. less confusion by having just one name across the board
Cons: 1. Need to add code to handle upgrade which involve re-writting mnesia meta data
2. Need to make changes in old code to be able to talk to new node "dcos-net"
3. More code more chances of error

Sergey Urbanovich Avinash Sridharan Deepak Goel met and decided to go with simple approach and take the complex one in future

We decided to keep navstar as node name. It's the simplest solution. And almost no one will see this node name.
