I cannot see any reason why this would happen - I thought maybe there was something in /etc/rc that would do it, but there is not. Further, the reversions seem random and irregular - happens in some jails, doesn't in others. I have witnessed this on multiple jails in multiple different physical machines, on versions from 4.4 to 4.6.2. Anyone have any ideas why this happening ? Has anyone else seen this ? Perhaps /dev/null is not the only one this happens to, but just the most noticable one ? (many programs break when /dev/null is 0600) _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
