Given that actually supporting the "options" resolv.conf option isn't all that easy (it would require having the update.d/libc script combine all the "options" lines from all interfaces, and somehow dealing with any duplicate options found, etc.), I'm guessing that the best resolution here is to edit resolvconf(8) so that it just lists explicitly the dns-* options that are supported in the interfaces file (and only refer to resolv.conf(5) as a source of additional details about how the resolver library handles each of those specific options).

(Related to the discussion in LP: #990660, this revised "ifup" description could also include some sort of mention that the "dns-domain" and "dns-search" options are merged together by the update.d/libc processing.)
