Before HP-UX 10.10, you could only use nsswitch.conf to configure the 
order of resolution for the hosts source. From 10.10 on, you can also 
use nsswitch.conf to configure resolution order for the services, 
networks, protocols, rpc, and netgroup sources. hosts: dns 
[NOTFOUND=return] nis [NOTFOUND=return] files"
