[Pkg-dns-devel] Bug#845378: unbound: Resolvconf script is not executable

Hello,

But when the executable bit is not set and resolvconf is installed, the
user ends up with no usable nameserver configuration after installation of
unbound, because resolv.conf only contains 127.0.0.1 (for the local
unbound) as nameserver entry and without further configuration unbound
does not know how to resolve names. That is, names cannot be resolved
anymore. Though this is not a big problem when no other package is
installed in the same "apt-get install" or so, it must be considered that
maybe other packages needing network access for configuration are
installed in the same apt-get run. So, the executable REALLY should be set
before unbound is started for the first time.
