create mask is a bit wise AND with the permissions to anything not set 
in the mask will not be in the final permission set.

force create mode is a bitwise OR so anything set in the mode will be 
included in the final permission set.

For example,

    create mask = 0644

means that group and other will not have write or execute permissions on 
ewly created files.  They might have read.

    force create mode = 0640

means that the owner will always have read-write permissions
and that group will always have write permissiom.

Hope this helps.

cheers, jerry
