Oops - reading failure on my part, sorry. But then I guess the converse problem is, what software makes assumptions about the difference between i386-linux-gnu and i486-linux-gnu that will hurt us? > > > I'd say any such assumption in those packages is buggy, per above. > > Yep, software is buggy.

Maybe, but considering some of the features lacking in i386, that could be a pretty severe regression, causing the system to fail the "fit for purpose" test. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
