Very close, it's /etc/securetty. By default, RedHat only allows root
logins on the console, which from a security standpoint, is a Good
Thing(tm). It is ALWAYS better to log in as a normal user and su (OK,
almost always, but I won't get into exceptions).

What I usually do to avoid this is to add the lines:
PATH="$PATH:/sbin:/usr/sbin:/usr/local/sbin"
export PATH
to root's .bashrc (/root/.bashrc) file.
