is it really useful to use chroot? (was: bind running as root in Mandrake 7.0)

[Carlos Carvalho]

I wonder if running bind (not as root, of course) in a chroot jail is
really worth the hassle. If you give it a correct uid/gid it'll only
have access to public read-only files after all. If it were just a
config option it'd be fine, but there's the mess with libs et. al.
that does need some determination to overcome...
