title: embedded linux with busybox auto-login
body: <p>I need to make a QT app to run on the startup of an embedded linux system that I made. I have access to the system via serial port ttySAC0. I tried adding the app to inittab , it runs but tslib is not working, probably because it can't find the environment variables it needs to work because I'm setting those environment variables in the /etc/.profile file which runs after user login. I need to auto login a user so the environment variables are set so tslib would work, or a way to set those environment variables without logging in. The system is made with buildroot and busybox.</p>
