Yes, but you can assign 'daemonÄ users to subsystems or single Daemons. A
good example is qmail which uses quite a few users and groups. If this is
done right you dont need world writeable directories on your firewall, you
can assign each subsystem a secured context (at least on the filesystem).
This is better than running everything as user nobody.

Greetings
