[news.admin] Preventing storage waste by crossposted messages

news@m2xenix.UUCP ( randy) (10/30/88)

I admin a small system with a selective newsfeed.  E.g.  I want to receive
comp.lang.modula2 but not comp.lang.pascal.  Unfortunately, it seems that when
someone out there in netland posts a message to both groups, I store two copies
of the message.  rn is kind and only shows one, but the directory is there for
the unsubscribed group and it has the message in it.  As I run a looong expire,
this eats disk.

As I subscribe to a limited selection of groups, having !comp.lang.pascal (and
zillions of other groups) in my /usr/lib/news/sys seems like a neverending
maintenance task.  I am sure there's a normal accepted practice to accomplish
this (or better yet, I have misunderstood something somewhere), so please let
me in on the secret.
