spamassassin-update can't open '/etc/conf.d/spamd': No such file or directory ```

The package spamassassin-3.4.4-r2 contains the file etc/periodic/daily/spamassassin-update which contains the following:

#!/bin/sh

set -e

. /etc/conf.d/spamd
pidfile="${pidfile:-/run/spamd.pid}"

if [ -f "$pidfile" ]; then
        _pid="$(cat "$pidfile")"
fi
/usr/bin/sa-update
if [ -n "$_pid" ]; then
        kill -SIGHUP "$_pid"
fi

But since there is no file /etc/conf.d/spamd the following error is generated once a day:

/etc/periodic/daily/spamassassin-update: .: line 5: can't open '/etc/conf.d/spamd': No such file or directory

It is likely that the intended purpose is to run sa-update once a day, but that now fails.

Two remedies are suggested, either one of them would be sufficient:

1. Change the etc/periodic/daily/spamassassin-update file so that it checks that /etc/conf.d/spamd exists before trying to source it.
2. Make sure that the file /etc/conf.d/spamd is created (can be empty) during package installation.
