So I kept the default hostname but also did something differently: choose `No` to `Update the hostname, hosts, and resolv.conf files?`. That seemed to work, so I decided to try a different hostname and still choose `No` to that question about updating hostname, etc. The result? It also worked.
My question now is: what does choosing `Yes` to `Update the hostname, hosts, and resolv.conf files?` do? When would I need it? How would I make it work?
Maybe that deserves creating a new question thread. Let me know.
Thanks!
