Netgroup support of ipv6 in Solaris/Linux

Found it. 

Solaris doesn't do reverse lookups for ipv6 in DNS unless there is an entry for ipnodes in nsswitch.conf. Since we are probably using a template in jumpstart from years ago, we didn't have it.

Once we added:

Ipnodes: files dns

Everything worked.
