Package: bacula
Version: 5.2.6+dfsg-9
Severity: important
Dear Maintainer and Developers,
bacula is unable to use tape drives on Debian kFreeBSD.
Using tape drives within bacula works with the Linux Kernel on amd64 and
sparc without any problem. Native FreeBSD with bacula works too.
bacula-sd is able to use disk storage without problems. But no tape drive.
This problem is only reproducable on kFreeBSD Systems!
The hardware works with kFreeBSD, I am able to use the tapedrive and the
changer with the mt, mtx and tar commands without problems.

then write 1 records and an EOF, then rewind,
