Well, it would do some, but for the greatest effect, you would need:
  dump + rm -rf * + restore
That would get it all.

You could be really extreme and do:
  dump + newfs + restore 
if you wanted to, to be sure of a clean file system

You would not need a reformat (though some people really mean newfs
when they say reformat) and you would not need any reinstall.  But,
if you did this on the root partition, you would have to to the
restore from some other boot such as on a different disk or from
the fixit utility on the installation CD.   That shouldn't be
necessary for any other file system unless you foolishly put /sbin
in a partition other than /  (root).
