hmm ok ok ok what about this. ;oP this gets better,

how about moving the su executable to a dedicated directory and
denying to "other" users permission to acces or list that dir?

for example.... something like this.

mkdir /bin/SU

mv /bin/su /bin/SU/su

and then add an alias system-wide

alias su /bin/SU/su

so if the directory /bin/SU is locked for certain people,
they would get no access?
