The old machine was decommissioned, so it seemed like a good time.

This wasn't the first time I tried an upgrade though. I hopped to 2.2.x
sometime around 2002 and found that whenever the machine was shut down
(not necessarily a crash), big chunks of overview got eaten with the
usual nasty active file and article-exists problems, so I had to keep on
doing overview rebuilds: so I downgraded again. This certainly is not
happening anymore: I even had a sudden power failure and everything was
fine afterwards, I think. (Part of this may be explained by the battery-
backed hardware RAID array the thing is now sitting on, but not all of
it.)

Also I wanted an excuse to try to use INN 2.x's pluggable
storage+overview architecture to hack up a PostgreSQL-backed storage
method, so I can try out its full text search facilities. (Why not just
rely on google and gmane? A combination of geekitude and the existence
of private hierarchies that aren't on either. But mostly geekitude.
Overview maintenance should be a piece of cake this way as well. Yeah,
it eats disk space, but I have lots of that free.)

Yes.

I was waiting to see if it crashed. No crashes. It works. (Of *course*
it works. Russ is congenitally incapable of perpetrating bugs. :) )
