Hello,
I just wanted to summarise and archive a conversation that I had with Peter yesterday on the phone:
We were talking about what mechanisms would be best to distribute the database on a daily basis. There are two options of which the first one is a downloader script which is called by systemd or cron on a regular basis, downloads the database, verifies it and done.
The second option is to use the package updating mechanism of distributions, i.e. sending a daily update of a package with the latest version of the database. That way, no extra configuration for systems behind a proxy and without any access to the internet would be necessary.
I personally do not think that any distribution would be able or willing to push a daily package update regardless of its size. There is no precedent for it in any distribution I know, but Peter was going to check with Debian if this is a possible path and report back.
Best, -Michael
