Hello, I have been using pam_devperm for a long time. If pam_devperm is configured like I did, it causes that, when a user logs in on :0, the permissions and ownerships of some device nodes in /dev are changed so that the device file belongs to the user on :0 and has permissions 600. Now, I upgraded to a new OS version and found, that after logging in on :0, some of the device file have permissions 660, not 600. It seems that, after pam_devperm has changed the permissions to 600, some other process resets them to 660. How can I find out what is changing the device permissions?
