This is very hacky, but I believe you can get the effect you want by having an admin process auto-start at host startup, identify itself, and then set parts of its own /proc/ process ID tree as world read/write. I think this will give you the "destroyed even at power failure" impermanence you are l,booking for. I know it is not in the normal layouts (like /var/run/ would be), but we are working around limitation s imposed by Windows. -- Erik -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
