This is a long shot, but is SELinux or AppArmor enabled on that box.
Neither of these security tools is enabled by default on Debian 8, but...
No, those are not enabled.
Also, since Debian 8 is now initialized with systemd(8), this is also a
possible detail that the devil has taken control of...
That may be. systemd makes me jump through a lot of hoops I didn't used to
have.
This particular machine is going to run "headless"; it's being shipped to
a network affiliate, where it will function much like a satellite receiver
in that music and network voice tracks will play from the box, which will
fire relays from time to time to call for local breaks, ID's, and bumpers.
It replaces another Rivendell box I built in 2007 which has been running
there for the past ten years.
Under Debian 8, the Rivendell daemons are started by a cron job runnig as
"root" that first waits 30 seconds for everything else to start.
Then another cron job running as 'scott' starts a VNC server, which
creates a virtual desktop via .vnc/xstartup, one line of which launches a
Perl script called rdairplay.pl that starts rdairplay on the virtual
desktop and loads and starts the log for the current day. Timed events
within that log are then used to get it to run more or less on time.
It's quite weird that 'scott' can write /dev/ttyUSB0, but 'scott' can't. :)
Yup. It reminds me of the ten Zathras brothers ("well, nine, now") on the
TV show "Babylon 5", who all have the same name, but with subtle
differences in pronunciation ("Oh!!! You did not meet ZATH-ras... you met
ZATH-ras!").
