Dropbear requiring passphrase

SUCCESS!

Login attempt for nonexistent user. I looked around and found the link
below.

http://comments.gmane.org/gmane.network.ssh.dropbear/1170


Ultimately, I had to include several libraries including some I believe
were not mentioned on that list. Attaching results of `find /lib` to
clarify the list. I know a lot of that isn't necessary for dropbear but it
is my /lib none the less.

It was also necessary for me to move /etc/passwd (and I happened to move
/etc/shadow in case) and I needed to edit /etc/passwd to have root shell as
/bin/sh instead of /bin/bash.

I think that's relatively complete. It works now. dropbear -E -F was highly
useful. I will be pairing down my /lib later.



Thanks for the assistance, it is functional now.
