I've just reinstalled my DAppNode and while I was plugged in with monitor mouse keyboard I wanted to carry on configuration in that specific setup.
(in my setup and headspace it would be so much more convenient to continue)
I understand GUI consumes resources, so surely not by default. Wish I knew there was some magical "apt get install GUI".
Ended up using an old laptop to connect to WiFi and never installed GUI. Would be practical.
