I agree completely with Christian. Although I have yet to implement any
such system, I had already identified the problem as a result of learning
the code, and the behaviour of 1-wire devices.
By the way, although I have been absent from this mailing list for a while,
I have been getting ready to do some work with this project. I think I
have identified a problem - at least under Fedora Linux - whereby owfs
started in normal - daemon - mode does not release from fuse correctly when
the daemon process is killed. I am pretty sure that this is because the
signal handler is not set up before daemonising the process. I swapped the
order of LibStart() and set_signal_handlers() <or whatever it's called,
sorry don't have access to the code right now> and this seems to correct
the problem. Does this make sense ?
