Yes, that's right, it's "as installed" xubuntu 17.04.

No, it simply returns nothing, no error.  'host esprimo' still returns
SERVFAIL.

No, 'host esprimo' still gives SERVFAIL.  However 'getent hosts
esprimo' works.

As I said I am going to add 'search zbmc.eu' to the file
/etc/resolvconf/resolv.cnf.d/head which will fix the problem for the
moment.

I'm quite happy to do further tests if they will help find what the
fundamental issue is.
