- install $PREFIX/etc/rc.d/innd.sh (start and stop)
- change group of $PREFIX/bin/rnews from uucp to dialer to work around
a problem when using inn with uucp (rnews is not world-executable to prevent
injection of faked articles)
- don't install binaries in $PREFIX/etc
- use /var/{spool,}/news/tmp instead of /var/tmp for rnews, otherwise
rename will fail
