MD5 passwords in Red Hat Linux 6.1

[Eugene Morozov <jmv lucifer dorms spbu ru>]

Hello,
Recently I realized that entering first 8 characters from my root
password is enough to log in as root although I've enabled MD5
passwords in installation program.  Also I've added two other users
during installation.  After looking through /etc/shadow it seems that
root's password isn't md5 although passwords of other two users are
md5.
Is it correct behaviour?
Eugene
