# Script to create /var/console/USER tag files compatible with pam_console
#
# Still needed as of dbus-1.2.12, which uses these files for the at_console
# check. You'd think it would use ConsoleKit to determine that, but it seems
# like they are not keen on dbus having to send a dbus message to figure it
# out.
