Bug#773752: gdm3: GDM3 pollutes system logs with user session output under systemd

[Vincent Danjean]

Package: gdm3
Version: 3.14.1-7
Followup-For: Bug #773752

  Hi,

  I suffer from this bug since I upgraded several of my machines/servers to
jessie. It is a pity this bug has not been handled before jessie release. It
should be fixed ASAP to go into a point release.
  In addition of the flooding of /var/log, the current behavior also have a
strong effect on the usability of 'logcheck'. To my knowledge, there is no way
to filter in logcheck messages from user application (Gtk, ...)
  Due to the break of logcheck usability, I'm increasing the severity of this
bug. Monitoring a machine with logcheck where there are graphical user sessions
is not doable in jessie anymore. For me, this is a serious regression with
security implication.

  If there is an easy workaround (as modifying a config file but not
recompiling the package with the suggested option) to avoid user log in syslog
or to filter them automatically in logcheck, please tell us and downgrade this
bug severity.

  Regards,
    Vincent
