Great job tracking down the issue and opening the bug reports.

Seems AI is good for something. You feed it enough data, scrape every 
corner of the internet, disregard copyright and then buy all the used, 
historical and cultural books in every language you can find, 
destructively rip the bindings off, and feed them into a scanner to get 
eveery last scrap of information, destroying culture and heritage along 
the way without preserving the text, and balloon energy consumption by 
TWs (TeraWatts, not Tumbleweeds) of compute emitting gigatons of CO2 
causing glacier collapse in the Himalayas -- and AI makes a pretty good 
search engine for solving computer problems....

It will be interesting to see what comes out of the bug reports and why 
the defaults are what you found. That's frustrating when it, e.g. "works 
fine with nfsv3" but not with nfsv4.

That also reminds me I have an old tower in the bone-pile that still has 
SUSE 9.0 Pro as the OS. I don't think I've booted it in 20? years. But 
unless the caps have gone on the MB, I bet it starts right up, on a 
system with a whopping 256MB of RAM :)
