Team, As a long time static /dev user the only thing I've noticed updates making a mess of is /dev/snd. I've not traced that, I know what it is and how to fix it. Its faster to fix it now and again that it is to establish the root cause. -- Regards, Roy Bamford (Neddyseagoon) a member of elections gentoo-ops forum-mods arm64
