[systemd-devel] [RFC][PATCH v3 0/2] journald: add support for wall forwarding

[Sebastian Thorarensen]

These patches add two new options for journald.conf:
 * ForwardToWall (default yes)
 * MaxLevelWall (default emerg)

When ForwardToWall is yes, journald forwards all log messages equal or
below MaxLevelWall to utmp_wall(). This can be used to send emergency
messages to logged-in users. A forwarded log message looks like this when
it gets written to a user's terminal:

Broadcast message from systemd-journald at hostname (Wed 2014-03-05
13:00:00 CET):

some-process[4711]: This is an emergency log message from some-process!


See
http://lists.freedesktop.org/archives/systemd-devel/2014-March/017610.html
for v1 of this patch.

Changes since v3:
 * Added missing documentation of new kernel parameter
   systemd.journald.forward_to_wall= to kernel-command-line(7) and
   systemd-journald.service(8)

Sebastian Thorarensen (2):
  utmp-wtmp: allow overriding username on wall
  journald: add support for wall forwarding
