Subject: [PATCH] unbound: Enable systemd support and install systemd units
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Install systemd socket and service unit.

`--enable-systemd` is needed, as otherwise [the service unit times
out][1].

Also, as we do not store the trust anchor in `/etc/unbound`, RUNDIR in
Unbound’s terms, add `/var/unbound` to the unit’s read/write path.

This does not have an effect yet, as mxtools installs
`/etc/systemd/system/unbound.service`.

For socket activation `use-systemd: yes` has to be set in the
configuration file.
