Well, I said AFAIK and I'm definitely not an expert in this area either
I've just noticed this happening when I do and apt-get upgrade, and no, I don't like much either.
Hopefully someone who knows for sure will shed some light on this. I've just solved it by purging the services/servers I don't need.
EDIT: Thought I saw it somewhere http://www.debian.org/doc/manuals/se...3.en.html#s3.6 under 3.6.1 Disabling daemon services
