I have a subdomain NS record which looks like this:

NS home ns1.nameserver.com
NS home ns2.nameserver.com

I'd like another subdomain super to point to the result of this NS name, but when I do:

CNAME super home

The name doesn't resolve.

This is a machine configured with dynamic DNS, hence home points to a 3rd-party dynamic DNS provider. To save myself the trouble of updating multiple dynamic DNS names, I'd like to simply have super resolve to the same IP address as home.

Is there a way to do this, or do I have to also configure a dynamic DNS NS name for super which is updated separately?

Shortly: yes.

Longer: This is a common misconception. CNAME points not an "NS record", but it points to all record type with the given name in the actual domain.

So, if you have a CNAME super home, it will point to all record type, if it is NS, A, or any other.

    FWIW: In order to get things working, I had to use the FQDN in the CNAME like so: CNAME super home.mysite.com. – Naftuli Kay Dec 4 '13 at 1:21
