The output of the dump is controlled by a command-line switch (-f).  
In the absence of the switch, it defaults to $RMT, but that is rarely
applicable any more.  Soft updates do not affect this.

That is not an issue.  Dumping a live filesystem is, but having soft
upates active on the filesystem does not make things significantly worse
than they would have been anyway.

Is it possible that your dump went to /dev/rmt because you failed to
supply an alternative destination?
