I am a noob, so please be patient.
What does the above quoted section mean?
Up to now I had to use the root user called “pi” to do everything:
a) connect via SSH
b) execute root commands on the shell
Using any other user than pi actually caused issues and I was forced to use “pi”.
See the solution from schoetju here:
On the other side I have read that on a raspi generally it is not advisable to keep a root user called “pi”.
So is there a way to create and use a new root user other than “pi” and disable “pi” afterwards?
