nosuid option for '/'?

[Art Lemasters <alemas@rmi.net>]

     Do any of you see any potential problem with putting the
'nosuid' option for the '/' directory in /etc/fstab?  I'm trying
to follow a Linux security How-To, but am less encouraged to
implement it after reading more about it (e.g., that it might
be less secure to do so with perl-suid implemented, even though
perl-suid has been removed from this sytem).  And if nosuid is
a good thing for this system, can it be implemented for the
/home directories only, without doing it for the whole / directory?
