Yeah, that's fair comment.  Something like this:

#!/bin/rc
rfork E
if(~ $#* 0){
	c=`{ls /srv/cwfs*cmd >[2]/dev/null}
	h=`{ls /srv/hjfs*cmd >[2]/dev/null}
}
for (i in $* $c $h)
	echo dump >>$i

Perhaps we call it fsdump to go with fshalt?

I did think about this but figured I'd do it separately (if at all) in
the interest of keeping the patch small and focused.  Anyway, might
be moot now.
