I'm having a bit of trouble with my home server (running Debian 7.7).
When trying to schedule a shutdown, the following occurs:
serverbox:~ $ sudo shutdown -h +10 Broadcast message from root@serverbox (pts/0) (Tue Nov 4 23:56:52 2014): The system is going DOWN for system halt in 10 minutes!
... Which is great, except the terminal does not return. Shutdown warning messages are still shown, but the terminal prompt does not return. Ending the SSH session or pressing Ctrl+c will result in the shutdown being cancelled.
Can I somehow prevent this behavior? Is this even supposed to happen?
