Out of interest, why do you want to set the owner of files to foo? If all
the users are members of the group "bar" it doesn't matter who owns them
(unless you want all users to be able to change permissions on the file, I
suppose).

Luckily, if the user has a private group, their default umask will be 002,
which is exactly what you want. This is exactly the situation where Red
Hat's user private group scheme comes in useful!
