How can I do this?

Hi: I have a filesystem called /photos whose files and subdirs I want in group "users" and with permissions: anyuser:users rwxrwxr-x at all times. That is, I want all users able to read, write, create, and destroy these files at will. I can do this with recursive commands to change the perms, but when a user creates a new file, it is created with that user's umask. How can I make the filesystem have a umask that overrides the users' umasks? Thanks for input. -- _____________________ Christopher R. Carlen crobc@earthlink.net SuSE 9.1 Linux 2.6.5
