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

[Sebastian Thorarensen]

Hi,

I want journald to send emergency messages to logged-in users, and I think
this is a general enough way to do it.

These patches adds two new options for journald.conf:
 * ForwardToWall (default no)
 * MaxLevelWall (default emerg)

When ForwardToWall is yes, journald forwards all log messages equal or
below MaxLevelWall to utmp_wall(). A forwarded log message looks like this
when it gets written to a users 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!


Comments? If you think this the correct approach, please consider applying
these patches :)
