I feel very uneasy about setting a precedent where packages can 
reconfigure unrelated packages just by being installed. I might have 
let myself be convinced that this is an acceptable price to pay for 
mDNS resolution by default on all Debian installations, but systemd 
would still require manual configuration anyway.


Cheers
