See http://www.elinux.org/images/2/2a/Using-buildroot-real-project.pdf
slide 25. You can use the post-build script mechanism to tune
the /etc/passwd file to set a root password.

I once thought of adding a Kconfig option for that, but it would mean
that the root password would be stored as clear text in the .config
file, which probably isn't that nice.

Should we make the default 'root' password be 'root' so that it is
non-empty and it works with Dropbear? Or simply add a FAQ entry
which explains this problem? Other ideas?

Best regards,

Thomas
