Given the need to handle file attributes and other xfs file extensions I 
don't see
how a program that dumps a xfs file can produce a dump tape compatible with 
the
current linux dump/restore.

I think a better solution would be to add the xfs ioctl'shat 
xfs_restore/xfs_dump need
to the  ext2 file system.  Not all the xfs_ioctl need to fully work they 
just need
to return reasonable default values.   That way their need only be one 
dump/restore program for linux.

I understand the wish for all dump/restore programs to work the same way
but given the different capabilities of the various unix file systems that 
just
not possible.
