Yes, the RTEMS kernel is in every binary. > 2.

RTEMS is a single process multiple threads system. So, essentially you have one user application which is linked against the kernel. The application can start multiple threads to distribute its workload, but cannot start other processes. The CLI, i.e. rtemsShell, is in its core just a text parser which then calls different C functions based on user input. It does not start other processes like a Linux shell would. I don't think adding tools like RPM is easily possible because many of the standard Linux libraries are not available on RTEMS. Cheers, Jan > 3.
