Hello, With opensuse-11.1 and kde4, I have seen three times on two different boxes that the mode of /dev/null was changed to 600. This breaks lots of scripts, which assume /dev/null is writable by anybody. The timestamp of /dev/null is also changed. Since chmod don't change the timestamp, this means the file is removed and recreated. When this happens, I see the following entries in /var/log/messages: Mar 6 15:03:16 raven polkit-grant-helper[13820]: granted authorization for org.freedesktop.packagekit.system-update to pid 4407 [uid=1000] [auth=root] Mar 6 15:03:22 raven shadow[14072]: default group changed - account=nobody, uid=65534, gid=65533, old gid=65533, by=0 M What is polkit-grant-helper and what kind of system-update is it doing? And why is it removing and recreating /dev/null? Any ideas? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
