I have added a tape drive to a SuSE 10.3 system to allow users to backup
databases. When I first tried to use the tape drive I found it was owned
by root with a group of disk and permissions of 660. I changed the
permissions to 666 to allow everyone access. For a few days of the tape
drive was assessable by the users. Then today a user was not able to
access the tape drive. I found the permissions had been changed back to
660. It seems some system program changed the permissions back. How do I
inform the system to allow all users to access the tape drive?

I do see that there is a /etc/udev directory and in the rules files I
found “TAPE” listed several times. It seems SuSE 10.3 may indeed use
udev to control the tape permissions.
Now I will hae to try to figure out how udev and its rule language work.
