Can you resolve hostnames with an empty "/etc/resolv.conf"?
Have you rebooted since creating that empty file?
The second question's because I've just installed connman and it has
$ cat /usr/lib/tmpfiles.d/connman_resolvconf.conf
d /var/run/connman - - - -
L+ /etc/resolv.conf - - - - /var/run/connman/resolv.conf
So a "/etc/resolv.conf" symlink will be created no matter what.
AFAIUI, connman acts as a dns proxy by default.
1) To set a global nameserver
Edit "/etc/connman/main.conf" and set
"FallbackNameservers=nameserver_ip_address[,nameserver_ip_address_2]"
2) To set a "your_service" nameserver
Run "connmanctl config {your_service} --nameservers
{nameserver_ip_address} [{nameserver_ip_address_2}]"
