Package: vdr-plugin-alcd
Version: 1.0.0-6
Severity: grave
Justification: renders package unusable

*** Please type your report below this line *** on c't VDR 5.0 (not sure about others), /dev/ttyS0 belongs to the group dialout. For the
alcd plugin to work, vdr must be able to write to the divice. As the vdr user is not part of the dialout goup, this will obviously fail as
the permissions on the devive node are 770.

Obviously there are multiple ways to fix this:
  - make vdr part of the dialout group (not ideal in my eyes)
  - edit udev config on installation to:
    + make the devnode 777 (not ideal in my eyes)
    + make all of subsystem tty belong to the vdr group
     (acceptable only if all Activy variants have no serial port.
      I've done this on my Activy 300 as it does not have any other serial ports)
    + only change ttyS0 to belong to the group vdr
      (ideal but I did not bother)

My edit of /etc/udev/permissions.rules follows:
#SUBSYSTEM=="tty",                              GROUP="dialout"
SUBSYSTEM=="tty",                               GROUP="vdr"
