Bug#810608: systemd-sysv: on shutdown, fails to inform users that the system is going down

[Francesco Poli (wintermute)]

Package: systemd-sysv
Version: 228-2+b1
Severity: normal

Hello,
I noticed a feature that systemd seems to lack.

When the box is being shut down (reboot or halt or poweroff), users
are not notified in any way of what is happening.
For instance, any remote user (connected via SSH) is correctly
forced out of the system (provided that libpam-systemd is installed
and OpenSSH has UsePAM enabled, see bug #751636 for the long
discussion about this), but there is no indication as to why
the user was kicked out.

On boxes that have sysvinit as PID 1, the users get an informative:

  Broadcast message from root at HOSTNAME (pts/0) (CURRENT TIME):

  The system is going down for reboot NOW!

or

  Broadcast message from root at HOSTNAME (pts/0) (CURRENT TIME):

  The system is going down for system halt NOW!


Could this feature be implemented in systemd as well?
It should be easy to add an appropriate wall(1) invocation
on shutdown. I hope it can be done soon.

Thanks for your time!
Bye.
