Scott: it was me. See below.

Yes, that's a jail.
The wrong jail.
The right jail is bacula-sd-02. On that jail, we have:
[root@bacula-sd-02 ~]# sysctl kern.securelevel
kern.securelevel: 2
After going back into the host, I set:
$ sudo iocage set securelevel=1 bacula-sd-02
Property: securelevel has been updated to 1
After restarting the jail and getting back into it:
Success.
[root@bacula-sd-02 ~]# sysctl kern.securelevel
kern.securelevel: 1
[root@bacula-sd-02 ~]# mtx -f /dev/pass7 status
Storage Changer /dev/pass7:2 Drives, 47 Slots ( 0 Import/Export )
Data Transfer Element 0:Full (Storage Element 1 Loaded):VolumeTag = 000001L4
Data Transfer Element 1:Empty
Storage Element 1:Empty
Storage Element 2:Empty
Sorry for the noise which would have been reduced if I'd gotten my sysctl on the right host.
FYI, Warner Losh got me through it by issuing dtrace commands on the jail host:
dtrace -n 'fbt::securelevel_gt:return {print(args[1];)}'
