[Bug 990660] Re: dns-domain in interfaces appears as search in resolv.conf

[Jeffry A. Spain]

> The distinction between 'domain' and 'search' should be immaterial;
the only difference is that a 'domain' option allows only a single
domain name, and 'search' allows multiple domains.  So the use of
'search' for a single domain is not a bug, and is more consistent with
the case in which multiple domain names are specified.

While I agree that the functional difference is perhaps immaterial, I
would argue that mapping both "dns-domain" and "dns-search" in
/etc/network/interfaces to "search" in resolv.conf serves only to
increase the possibilities for confusion and errors, particularly since
this mapping appears to be undocumented as well as unintuitive. For the
sake of consistency, it makes sense either to map "dns-domain" to
"domain" and "dns-search" to "search", or if you think the use of
"domain" in resolv.conf should be deprecated, then eliminate "dns-
domain" in interfaces. Thanks for your further consideration.

Title:
  dns-domain in interfaces appears as search in resolv.conf

Status in “resolvconf” package in Ubuntu:
  Invalid

Bug description:
  As recommended in the post http://www.stgraber.org/2012/02/24/dns-in-
  ubuntu-12-04/, I placed "dns-domain countryday.net" in an iface stanza
  in /etc/network/interfaces. The resulting resolv.conf file contains
  "search countryday.net" rather than "domain countryday.net" as I would
  have expected.
