Notes about openvas-scanner in Debian
-------------------------------------

The Debian package ships a working redis configuration file
(/etc/redis/redis-openvas.conf) and an openvas-scanner configuration
file (/etc/openvas/openvas.conf) that work together by default.

Since version 10 there is no longer openvas-scanner.service.

If you are not using systemd, then it's up to you to tweak the
configuration to get it to work. One possible way to get there
is to replace /etc/redis/redis.conf by /etc/redis/redis-openvas.conf,
restart redis-server and be done with it.
