Thanks and this must mean the fix for Ingo's issue was done by Christoph 
between v3.8 beta1 and beta2.

On recent linux distributions I get that those supporting them want to 
simplify their jobs and the less you ship officially the simpler it is.

With Ubuntu I 'suspect' some of what's happening are changes due its 
broadening adoption - as the windows linux subsystem, for example. I'd 
make a small bet the change in core file handling was done in part to 
better support such uses. The old core handling has issues too.

One of my other pet peeves with Ubuntu 22.04 is they've adopted snaps 
(code on VMs) as the up front supported code for shipped packages like 
firefox. OK, except, I have long run firefox against files located all 
over my computer's file system - especially off ram disks - and by 
default most such file systems are not accessible from within the snap 

Anyhow. Change. I believe too a younger generation is coming to the fore 
support wise. They see things differently. Most of us old time unix / 
linux users are getting on in years. :-)
