Thanks. I propose to add a default config file, which can be
overwritten when there's manual input by the user. We have taken the
same approach in rtems-littlevgl for the graphics configurations.
Initially, the services repo will have just telnet, and tftp and we'll
expand on top of it, taking feedback from devel as we progress.
