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.
