As others have noted here or elsewhere, this software has "debug" code turned on and that's likely also why you have these add'l menu options. Rest assured, they'll not remain in the public version. Then again, I don't see the harm in them. "Restart" is no different than holding the power button on the front panel. Both do an orderly shutdown. Pulling the power cord is bad on the filesystem normally but the 622 has a journaled FS, so it's not so bad....
