I'm stuck trying to get access to my tape drive / tape library from within my FreeBSD 11.1 jail.
Via /etc/devfs.rules on the host, I have set allowed the jail to see the devices:
$ ls -l /dev/pass8
crw-rw---- 1 root operator 0xb6 Dec 16 16:48 /dev/pass8
$ sudo tapeinfo -f /dev/pass7
cannot open SCSI device '/dev/pass7' - Operation not permitted
The same command on the host succeed.
$ ls -l /dev/pass7
crw------- 1 root operator 0xb0 Dec 16 16:48 /dev/pass7
(the original message had an ls of a different device).
