I meant the one where I conceded that the only think that it could possible protect against was a denial of service attack, from which we probably don't care. I just want to be certain that the emails are getting through. As the meaning certainly has not been. I do think I called a permision check in posix_open aka on /dev/ptmx a linux specific extension in that email. But seriously it was all about reducing the scope of the change. Reducing the size of the test matrix. I simply had not looked far enough to see if there was anything you could reasonable protect with those permissions. As I agreed with you that it was unnecessary I was just puzzled why you called what was essentially agreement with you deafening silence. Eric
