You can either set the root password in the buildroot configuration
(but it will be stored in the config file in plaintext, so for a
non-personal project that may not be ok) or you can update the
/etc/shadow file from a post-build script, see the presentation
http://elinux.org/images/2/2a/Using-buildroot-real-project.pdf slide
25.

I don't think I can help you here (no particular dhcp experience in
Buildroot) but I think it is useful for other developers if you could
paste some relevant parts of the log here.
