Funny thing..

I just duplicated the sysdiag bug shown below..  The system I tried
it on is running hpux 10.10, why would HP fix a security bug in 1994
in hpux 9.04, then release it years later in a new release?

Although, the system would not let me log in immediately since roots
.rhosts file was owned by the non-root user(me) who created it with
sysdiag, but since I was the owner of the file I could chown root
.rhosts then the system graciously let me rlogin as root without that
annoying password.

On a side note, if there are any SysAdmins out there using the
/etc/securetty file as a means to disallow direct root login, don't. It
also
has a "bug" that HP support never gave me a answer for.  If you
use xterm to login to your server it doesn't use the /etc/securetty file
so the tty is not secure, you can get a direct login as root without
any changes to the system.  I thought somewhere within C2 specifications
it talked about disallowing direct root login....
