To clarify: running news on multiple partitions is (naively) a breeze. However,
the same machines with the 64K inode limit tend to lack symbolic links. So
articles cross-posted over multiple partitions break (EXDEV) in the absence of 
special handling by the news software (which needs to copy, instead of link,
such articles). This is the reason why mods to the news software is necessary 
to do this kind of thing.

Such mods are available for B News to run on multiple partitions, but, as far 
as I know, and last time I looked, there were no such mods for C News. This is
a shame, because, IMHO, C News is a -must- for anyone trying to run a serious 
news site on a 3B2. We watched "ole faithful" B News rnews literally get 
buried under our incoming feed before we grudgingly made the switchover. And
feed-size, like entropy, does not -decrease- over time...

Cfctech (3B2/1000 Model 80, SysVr3.2.2) currently runs C News on 3 partitions
with the aid of my own hacks. Our full feed would have been down to a 9-day 
expire by now (if that) if we were still stuck on a single partition. As it 
is, we can manage 14 days comfortably. 

If/when I get things streamlined, cleaned up, and completely tested, and 
assuming the C News people are interested, I'll pass the mods along.
