Many of the in-tree daemons (bind, postfix) will gladly take a flag
to chroot() themselves. Anything else, chroot(8) will probably work
on (but that makes binding to ports more complicated).

As far as a hardening script... most of the things that those
scripts, like Bastille for RedHat Linux, do are the default for
NetBSD. We don't open ports in /etc/inetd.conf, we install a fairly
sane sshd.conf, so forth.
