+ The start_tdeinit wrapper is setuid, which means some shell variables like LD_LIBRARY_PATH
+ get unset before it's launched. However tdeinit is used to launch most of KDE, so such variables
+ should not be dropped. Therefore this wrapper for the setuid wrapper read the environment
+ and writes it to start_tdeinit's stdin, which after dropping priviledges reads it and uses it
+ for launching the real tdeinit.
