[Bug 1063639] [NEW] Resolver ignores search domain from DHCP server

[Msquared]

Public bug reported:

Although the search domain is saved to resolv.conf, the resolver is not
resolving hosts in the search domain.

Here I'm trying to ping a host whose IP is resolvable via the search
domain, but ping can't find the IP unless I add the domain name to the
host name:

user at accrec2:~$ ping kane
ping: unknown host kane
user at accrec2:~$ ping kane.jjhawkins.com.au
