--- Comment #17 from Robert Clausecker <fuz_at_fuz.su> ---
So yeah, the same approach also works on amd64.  To reproduce:

1. install archivers/star
2. make a zfs dataset and nullfs mount it somewhere.
3. in the nullfs mount, unpack the schilytools
4. build the schilytools by typing "make"
5. type

    star -c -v -f /dev/null -sparse . 2>&1 | grep sparse

   to find spurious sparse files.
