Using `dump 0af /dev/rst0 /' is not that complicated:

    option a:	``auto-size''.  Bypass all tape length considerations
		and enforce writing until an end-of-media indication is returned.

The tape names are quite strange. I have /dev/rst0, /dev/rst1, and so on.
/dev/st0 is a block device and will not work as expected.
