Bug#784238: systemd: emergency.service restart leads to unusable system

[Bernd Zeimetz]

Severity: critical
Package: systemd
Tags: security

Restarting emergency.service (as done by needsrestart) within the 
emergency.service leads to a prompt for the root password to enter 
maintenance, but neither entering a valid password nor pressing ctrl+d 
results into a login shell.

Even worse, pressing enter shows the prompt from the former shell and 
I'm able to get 'bash ... command not found errors' by entering various 
combinations of letters and hitting return often enough. So while the 
shell seems to be locked, it is actually possible to run commands within 
the shell behind the login.
