[SOLVED] /etc/resolv.conf vs. the DNS field in netctl profiles

I'm a bit confused about the current role of /etc/resolv.conf.  The Netctl profile documentation has a DNS field, so has /etc/resolv.conf become functionally obsolete when using netctl?  Or is /etc/resolv.conf still useful when you have multiple interfaces, as it specifies DNS servers for all interfaces?

From https://wiki.archlinux.org/index.php/resolv.conf:

dhcpcd, netctl, NetworkManager, and various other processes can overwrite /etc/resolv.conf.

The DNS field of netctl will simply allow you to specify what gets written to resolv.conf.  /etc/resolv.conf is still used by the system itself to specify nameservers.
