    base-files: resize only serial tty's in profile
    
    We don't want to run resize on non serial consoles. There's
    been an earlier attempt (6557787), so this builds upon that.
    
    The problem we're seeing is that if there is text buffered in
    the virtual console (like from a desperate user trying to
    enter login details), resize will get stuck while calling
      ioctl(tty, TCSETAW);
    
    Since serial consoles are named (not just numbered), this
    change limits resize's reach even further to run only on
    /dev/tty[A-z] (thus avoiding /dev/tty[0-9]).
