the setgid bit forces all files to be created with the group of the parent directory rather then the user's primary group. essentially it changes the file creation semantics from sysv to bsd. as for 755 vs 700 its a long and well known *nix tradition to create home directories world readable it encourages a sharing environment. users can always change the permissions on their home directory or any subdirectory they want to keep private. if your users are too dumb then you may have to do it for them. i think /etc/adduser.conf has a option for home directory creation mode (maybe only in woody's adduser..). just because redhat does something doesn't make it standard or correct. -- Ethan Benson http://www.alaska.net/~erbenson/
