Heh, I had to take a breath at chmod -x, it almost came out rm -f when I 
did it. Systemd, D-bus, and pulseaudio keep my pharmacist providing me 
with blood pressure meds.

This machine is stand alone. Not even any network, just a printer, 
scanner, burner, and turtle beach sound card. I thought it would be a 
fitting retirement for a 13 year old Tyan board.

I'll run a network cable and try the install script for studioware. Once 
I figure out what software I want to use, then I'll retry the SBo scripts.

Thanks for tips anyway.
