+# "fail hard if socket directories cannot be chowned to root or
+# chmod'ed to the requested mode if 'sticky' bit is requested for this
+# directory instead of just print a warning that will remain unnoticed
+# most of the times.
+# Set the define XtransFailSoft to restore the old
+# behavior to fail softly when socket directory cannot chowned/chmod
+# to correct user/group."
