It does -- as of yesterday :-)

If you can't upgrade to -current, I'll make a small patch available.  It
really wasn't that much work...

I'm also looking at the sizes of blocks written to the tape.  I think
I've got my TKZ09 (Exabyte 8500) writing variable blocks size - I'm just
testing it now.  I suspect that your TLZ06 is only writing 512 byte
blocks - an Ultrix cam_data.c says that it's capable of variable block
sizes.  When your machine boots, does your tape drive probe as

	tz0 at asc0 drive 5 slave 0 DEC TLZ06     (C)DEC rev 491A

or similar (ignoring the revision - I guessed the above from an Ultrix
boot message)?
