remove the commented-out line?

eek, who sets $restore_dir? Oh, sourcing common/dump does.
But nothing mounts $SCRATCH_DEV yet, right? So this seems
like a combination of incorrect, unnecessary & dangerous.
(_wipe_fs will re-mkfs anyway). I'd just remove it.

$tmp is /tmp/<our pid>
so /tmp/<our pid>.stream *really* shouldn't exist, and cleanup
should have removed it from the last run (with a different pid).
But I suppose it doesn't hurt to be sure...

Ok, wipe_fs does mkfs & mount. Could you add a comment?

same deal w/ the order of the redirects. More below too.
Otherwise looks ok.
