You do NOT want to do this. Both "buffer-writes" and "async-writes"
are pretty reliable ways to make any kind of end of tape detection
fail. If you want to issue an init command, then it's a
mt -f /dev/nst0 stoptions 0
to turn off all these "performance-improving" (and reliability-
killing) features.
If you are using an autoloader, it's trivial to patch the mtx-changer
script to perform such a command after loading a tape. Of course this
assumes that no other user is messing with the tape once it was
loaded - but that's a general assumption for bacula anyway.
