See my later email on this - it's a package that users have chosen to
install, because it's pulled in as a recommend. It's not currently
installed and enabled by default in Stretch.
I'm not sure if it does clash with Template usage - if you can start the
Template and have it automatically pull in security fixes that may
become part of standard usage.
What's certainly true is that it would be disastrous in a
TemplateBasedVM, (and pointless).
But that's a generic problem with any Debian based system now, that many
services start automatically once installed. We don't have a sensible
way of controlling this in Qubes at the moment, although there is a long
standing issue on this.
