Bug#776554: sulogin says "System Maintenance Mode", doesn't asks for a password if the /etc/passwd (or shadow) entry for the user is empty

Thu, 29 Jan 2015 01:09:39 -0800 

Package: Busybox
Version: v1.22.1

If the /etc/passwd (or shadow) entry for the user is empty, I invoke `sulogin' 
without arguments from an ordinary shell
prompt, it prints `System Maintenance Mode', rather than to ask user for a 
password "Give root password for system maintenance
(or type Control-D for normal startup)"

Here is a transcript:

  $ sulogin
  System Maintenance Mode
  $ /sbin/hello
  System Maintenance Mode
  $


I suggest that sulogin always ask user for a password even if /etc/passwd (or 
shadow) entry for the user is empty.
