On all Ultrix (2.x and 3.0) systems here, su(1) still cannot correctly track
super-user log.  The follow shows su(1) tells nothing about who has become a
super-user or who has tried su(1) command but failed.

	su < /dev/tty

Then a message like "SU:  /dev/tty" will be printed out on console, and
"SU:  /dev/tty Wed Apr  5 12:25:40 1989" in /usr/adm/sulog.  Any comments?
Perhaps, Ultrix's su(1), rexecd(8), rshd(8), etc. should do more checking.

PS: su "" < /dev/tty if there is a line "::0:0:::" in /etc/passwd!
