The libos loader finds each log buffer by looking up its eight-byte name in the init argument array, so a buffer the array does not name is never written to. Nova-core allocates six log buffers and gives all six a debugfs file, but names only three, so the other three can never read back anything but zeros. Name all six. RMARGS moves to the end of the array, which does not matter to a loader that searches by name.
