[luau] hacking

[Randall Oshita]

If I knew the root passwd and have access to a user account on a box,
can I sucessfully clean my trail (sulog, messages, etc) with all
entrances and activities I do to the box? If the audit was done only on
the box level , not pix logs or anything else.
Is there something that may log this that cannot be cleaned?
I remember seeing this on the list before but cant remember what date it
was. 
Just wondering.
