Hello,
some more 4k-bytes/sector fun today. dump(8) doesn't like the
4k-byte/sectors source devices. There is an output below as an example and
also related patch for the man page.
With restore(8), i did't encounter any problems when restoring dumps of
regular 512-byte/sectors filesystems to a filesystem residing on a
4k-byte/sector device. (I silently suppose that all sector sizes other
than 512 bytes are affected.)
