With the Fedora Linux world, the tape devices are owned by root with group disk. The default settings for the device are ug+rw. The system this is on is not running SELinux so the perm are quite a bit looser than they could be. bacula is a member of the disk group. The default install from a compiled src.rpm had the user and group as bacula. But the bacula user has no write privs on /dev/sg* as it's all owned by root. I guess I need to poke around in /etc/udev/* and come up with some better rules than owned by root. That's where it would need to be changed so the perm will survive a reboot. Hmm. Now that I think about it, the change needs to happen in the bacula-sd init script. That where the device name and ownership can be found and set since the start up is run by root. So the plan for now is to use the init script to parse the bacula-sd.conf file, extract the devices to be used and chown them to user bacula. On shutdown, they will need to be changed back to the original settings. I'll look at dumping that data in /var/bacula. > -- James P.
