[Pkg-aide-maintainers] Bug#366776: aide doesn't gracefully handle null dnsdomainname output

[Corey Wright]

experienced same problem here.  i'll pick up where craig left off (in the
email chain for bug 366776).

# dnsdomainname
<null>
# hostname
deuteronomy
# cat /etc/hosts
127.0.0.1       deuteronomy localhost localhost.localdomain
# echo '127.0.0.1 localhost' >/etc/hosts
# dnsdomainame
gigabit
# hostname -f
deuteronomy.gigabit

aide now works.  (at least an "aide --init" is currently doing something.)

this never caused a problem before (and i remember purposely setting it
this way in the past, but now i can't remember why).

i don't know how aide would handle a configuration with no dns domain (a
small home network, a standalone workstation, etc), and maybe that
configuration is technically incorrect, but i don't believe aide shouldn't
require such to function.
