Yep, just did that, and got a couple of failures for sparse-fiemap
on and ext3 and loopback ext4 file systems.
On a very quick glance, I think cp is OK and that the filefrag
matching is a bit brittle.
Attached are filefrag outputs.

$ rpm -q kernel e2fsprogs
kernel-2.6.35.10-72.fc14.i686
e2fsprogs-1.41.12-6.fc14.i686

Pádraig.
