Clarify DNS Nameserver(s)? prompt setup-dns
When prompted to enter a nameserver (or multiple name servers) it is not immediately clear if the nameservers should be space or comma delimited. If the ip addresses are comma separated, no error will be reported, but the /etc/resolv.conf
entry will (obviously) be malformed.
I propose simply adding words to the effect of "separated by spaces" to the prompt. Additionally a simple check could be added to check the input format before committing to file.
