When the first non-root user logs into the local console, the ownership is set to that user. When they log out, they are set back to the default ownership/permissions. The values used are specified in /etc/security/console.perms.d/50-default.perms. but you can create your own file to override the permissions you want. This is covered in the console.perms and pam_console man pages. Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
