That's an incredibly bad idea.  Setting programs to be SUID and/or
SGID when they weren't intended to be set and run so, typically opens
up major security vulnerabilities.  Yeah, don't follow random crud
advice you find on the Interwebs.  Heck, very first security
vulnerability I ever found and reported was when a particular *nix
provider made exactly that mistake, and in so doing, opened up a
significant security hole.
