comment Using ncurses for basic GUI on a process started inside an init script
OK thanks for this. I was thinking about implementing a separate application for the GUI and using IPC as you suggest but that involves a large amount of work. If all else fails I will try that

@goldilocks It is a busybox init system. Unfortunately there is no rc.local file. I do not need it to be portable at all. I will try the autologin approach for the time being and pray that a nicer solution is possible

comment What is the meaning of the errors from my cpio command?
thanks very much indeed for that comment - sudo id is root. If I call sudo find . | sudo cpio ... and omit the -c option then it works without any error. I never realised that I had to call sudo on both commands. I am still mystified why it worked without complaint in the past but I guess that is life. Thanks again for your help

Thanks for your answer. The second part I would agree with but I am calling this with sudo. And for the first part, why is it only starting to display these errors when it has been working without them in the past?

comment My process was killed but I cannot understand the kernel notice
On a run of strace I see no ioctl() calls inbetween my calls of open and ioctl using TIOCGSERIAL . It really does appear that either the open call is setting the SAK, or that the busybox implementation of setserial does not work properly. When I open /dev/ttyS0 the ASYNC_SAK bit is certainly set.

I finally managed to find a code based solution and I posted it on stackoverflow. I will add this answer here but I will accept your answer as this enabled me to identify the how and why of it all. Many thanks
