Bind is chrooted into directory /usr/lib/named and runs as user named.
Apache is chrooted into /usr/lib/www and runs as user wwwrun.
Exim is chrooted into /usr/lib/exim and runs as user exim.
...

There are even systemcalls in all flavours of unix for doing this.
There is (almost) no need to run anything as root.

Bernstein too has ideas too, how not to run things as root ...
Works under all flavours of unix, including MAC OS-X. I guesstimate
that works for some 70% of all servers.
