I haven't seen it.  So I looked and "man mount" said:

nosuid Do  not allow set-user-identifier or set-group-identifier
bits to take effect. (This seems safe,  but  is  in  fact
rather unsafe if you have suidperl(1) installed.)

It seems that people are thinking about it but they aren't quite "desktop ready"
yet.  And it looks like I need to spend a little more time preparing my floppy.
