What I would like is a message like you get on the console when someone su
to root. So if I am logged in as root that I would get the message from the
first console also in a ssh session.
It is not about trust, but in case of trouble it sometimes happens two
people are working on the same issue.
So sysadmin 1 log in and become root. He starts to do his thing. Then
sysadmin 2 read the same ticket and logs in also.
They are not aware that they both work on the same problem.
If sysadmin 2 become root and sysadmin 1 sees that because he saw the su to
root then he  could  notify sysadmin 2 that he is already working on it.

But set watch = (0 all all ) shows logged in users so that way sysadmin 2
sees that one is already logged in so it helps already. But the su message
would be nice.
