[ale] Multi-label names

[Todor Fassl]

Well, I could just disable systemd-resolvd and then create a 
/etc/resolv.conf in a text editor. But I'd rather not go backwards. I've 
mentioned before on this list that I rue the day I decided to switch my 
end users from debian stable to ubuntu. But I can't go back on that 
either. I'd like to get systemd.resolvd working.

Have you ever heard of this term, "multi label name"? I am thinking it 
means either an fqdn *or* an unqualified dn. So examples would be spock 
and/or spock.example.com.

host lookup for a non-existing, unqualified host name, it takes a long 
time to error ot. Say I have a host named spock. I can say, "host spock" 
and that comes back instantly. If I say, "host sopck" or some other 
typo, it takes like 10 seconds and I get this:

(through no fault of my own). It's listening on 127.0.0.1 and caching 
DNS queries. So trying to read the man page for systemd-resolv, I keep 
coming across the term "multi label names". I never heard that term 
before, don't know what it means, and it appears to be ungoogleable.
