[nsdispatch] hosts(5) does not override DNS lookup?

[LI Xin]

Hi,

Recently one of our local user has found that he was unable to use
hosts(5) to override "localhost" lookup that happens in DNS, while doing
rpc_clnt_create.  A preliminary investigate of this seems to be related
to nsdispatch, by replacing:

hosts: files dns

With:

hosts: files

in /etc/nsswitch.conf, it does not query DNS.

Before diving into NSSWITCH code, I'd like to know if this is expected
behavior?  Say, when we have a match in hosts(5), should we even bother
to query DNS if configured hosts: files dns?

Cheers,
