	If you have an extra filesystem to use, just stop news from running,
use du to identify some branch at the first level below /usr/spool/news
which has a large chunk of news volume (Ideal would be about 50%, but
whatever you can find under a single subtree), use cpio or tar to move its
contents to the spare filesystem, rm -rf that filetree on the original
filesystem, mkdir the top point of the subtree, and mount the new partition
on that point.  Remember to modify your boot-up scripts (/etc/rc and
whatever else it invokes on your system) so the new partition gets remounted
every time you boot, and to make sure that fsck gives the filesystem its
blessing (/etc/checklist).  At this point, you now have a fresh 64k inodes
for the aprox half of the news to live in.

	If your 3b2 is like my 3b1, df(1), mount(1), and some other things
may truncate the name of the mount point in reports, but if you KNOW where
things are, I think that everything will be allright. (My /usr/spool/news
gets reported as /usr/spool :-) (No - I'm not getting a full newsfeed -
thank God.)

	Also - be sure to mount filesystems in the right order!  If
/usr/spool is mounted on /usr, be sure to mount it BEFORE trying to mount
/usr/spool/news/<some_tree>

	Good luck - and remember that this hasn't been tried on a 3b2 by ME,
since I dont have one.

	DoN.
