Are you using host(1) command for this? If so, host(1) in
10-RELEASE does not respect 'options' from resolv.conf (there's
a note about this in it's man page); the system resolver (that
is, anything based on getaddrinfo(3)) should not be affected
though.

The reason for this regression is that host(1) is now based on
the ldns library, which doesn't currently parse the 'options'
directive (e.g. see [1]).

The solution is to add '-w 1' to the list of host(1) options.
Or to push the ldns folks to fix this.
