A better way would be something like the following.  This assumes su uses
PAM.  Add the following line to your /etc/pam.d/su file:

  auth     sufficient   /lib/security/pam_listfile.so item=ruser
sense=allow onerr=fail file=/etc/security/suauth.nopass

Then add the username of your mythfrontend user to
/etc/security/suath.nopass.

And I imagine you can configure your mythfrontend to run:

  su - -c halt # (or better yet /sbin/halt)

You can also probably achieve the same with sudo, but that requires another
package.
