Ugh.

Thanks for the gory details. You spoilt my breakfast ;-)

I jumped off that wagon about that time where details were being
"ironed out": once, I pushed the power switch shortly, expecting
the system to power down... instead being presented a message that
I wasn't authorized to do that.

"What the heck?" thinks I "I have physical access to that box.
I could smash it with a sledgehammer".

Looking into the problem, I came to the conclusion that, as long
as I can keep my Debian box dbus-free, all other things I don't
like stay away too.

Yes, if I want to do videoconf these days I have to start Firefox
under apulse (they manage to maintain Firefox for three different
platforms, but for Linux they can't do alsa/pulseaudio: quite
hard for me to stick to Hanlon's Razor, but I try). Other apps
whine that they miss dbus. If I really care about them (Emacs,
I'm looking at you) I do compile them with dbus configured out.
Bluetooth. No bluetooth. I don't care.

But those are minor inconveniences.

Thanks (this time genuine thanks!) to people like you: you help
me to stay informed without having all the pain myself :-)

Cheers
