-====== Run Programs with Root Privileges ======
+====== Do Not Run Programs with Root Privileges ======
+On a realtime system, you need certain privileges to run EEROS applications. This is for the fact that the ''Executor'' tries to change thread priorities and the scheduling principle to realtime characteristics. \\
+If you run your EEROS application without root privileges you will get a warning that this change could not happen and your application will most probably violate your realtime criteria.
+Do not run your applications or the built-in EEROS examples with root privileges! Change your system settings so that changing this settings are allowed for your current user, see [[getting_started:tutorials:rttest|]].
+Further, if your program tries to access device files, such as a mouse or a serial interface, change the permissions on this file so that your current user can access it.
