  Well, I did a few days ago:  See my message from 03/03
on "dump and nodump flag".  My point was, if we allowed dump
to use a generic filesystem traversal framework (like fts, but
also for unmounted filesystems) and did a clean job of it, then
it would be trivial to write dump for other filesystem types --
you'd just have to change the walker, and maybe some bits of the
dumped information, depending on the fs.

  I would like to write such a dump, and see if the reduction
to one less pass with a traversal makes up for the lack of
locality in the inode reads.

  But I'm afraid that will have to wait until after I write a
dissertation.  :)
