+	   if there is a system-wide 'users' group - so some distributions
+	   add an extra group for every user which lets the /etc/group
+	   file grow very fast and makes the admins life harder ...
+
+	   Activating this feture adds a function to the SUID flag on
+	   directories, which usually has no function at all:
+
+	   If the SUID flag is set for a diectory, all new files in that
+	   directory will get the same rights in the group-field as they
+	   have in their user-field.  So, if one sets both - SUID and SGID
+	   - on a directory, it will also work with a umask like 022 or
+	   077 and there is no more need for an extra group for every user.
+
