Looks sparse to me:
$ dd if=/dev/null of=test_sparse bs=1 count=0 seek=10G
0+0 records in
0+0 records out
0 bytes (0 B) copied, 1.4466e-05 s, 0.0 kB/s
$ du test_sparse
0 test_sparse
$ du --apparent-size test_sparse
10485760 test_sparse
Truncate would work too but unless there's a hidden problem with the
above I'll need more convincing to change it :)
