I'm out of my depth when it comes to the politics of all this. So I think I'm going to bow out now. I'd already got the solution to my specific issue (write a tiny "syncfs" program and call it from my script prior to taking a snapshot). While I'd like to try and help others avoid the same pitfall as me, I'm not motivated enough to blunder any further into this disagreement. Cheers, Alun.
