[Lxc-users] shutdown on dom0 warns containers

[Trent W. Buck]

When you run something like "shutdown -r 18:30" on a host, users will
receive a bunch of notifications via (I think) wall(1), like

    Message from root:
    The system will reboot in 180 minutes!

Unsurprisingly, if you schedule a reboot of the host system, people
logged into containers don't receive warnings.  But it would be awesome
if they did -- any ideas how best to achieve that?
