1. Not always these nodes require access to the admin socket.
2. In this mode, it is impossible to start a node without a tun interface. But I would like to.

Therefore, I have two requests, if I may:
Add the key '-noadminsock.'
Add the key '-notun.'

I encountered this with yggstack, so I ended up with yggdrasil-network/yggstack@ad93f2c

So if you dont need TUN or admin socket, you use yggstack instead.

EDIT: I even did reflect this usecase in the README :)

A more concise way to do this is to create a partial configuration file and then use -useconffile at startup instead of -autoconf. Yggdrasil will automatically fill in the blanks so if you don't specify a PrivateKey then it will generate one at startup.

For example:

{
  AdminListen: none
  IfName: none
}

Similarly you can add Peers, NodeInfo etc.

Hmm. I didn't know about "partial configuration".
