It's suid NEWS, not root. Though indirectly you can get root from that.
I know. Get news, modify rc.news file, run by root... :) This was
originally run as root so that I could have it create index files, as
this is no longer needed (I have news locally) tin is no longer suid root.

I don't have a group passwd, don't see the use other than convience.

Kinda strange way to do it, since have of slackware is made up of things
that should be in /usr/local/bin. Again, this is personal taste, so

The whole "r" program problem is always a pain. If you have a local
cluster of machines you run, you want people to be able to rsh back and
forth around them and not worry about having to type their passwords
again. Though you want to prevent any attempt at doing this from the
outside including if these users have + + in their .rhosts file due to
some "mistake".
