Ah, great point!  I had forgotten about this.

The main reason I want to write some filesystems to tape (while writing
others to holding disk) is that I have a config that backs up some
laptops at noon, delaying desktop backups until 9p.  If I don't
have enough holding disk space for one of the laptop's filesystems, the
whole job gets delayed until 9p (which can screw things up when the
laptop is no longer on the net at 9p).  I'm wondering if I specify for
the filesystems of the laptops to always be written directly to tape if
this would avoid this problem.
