Create home folder disk image of root user

I did a clean install of Mac OS ML and faced several trouble bringing my files back (some of them were missing, other had a less sign, with permissions problem... I then enabled root user and used migration assistant (there were no permissions problems anymore. But now, everytime I have to put root user and password to sign in, besides OS keeps asking for information and offering transfer options. I want to get rid of root user, but to have my files on the other user without having to use migration assistant again on an administrator user (wich will probably bring the permission error back).

Is there a way to switch or make root user files to be "magically transferred to the common admin user"?

Thanks.
