I don't really agree with it, but pitrery uses 'dd' with 'conv=fsync'.
As far as I know, there isn't a way to force 'rsync' to run an fsync()
at the end, and executing a 'sync' afterwards, while it should work,
seems likely to cause you a lot more troubles..
In the end, I wouldn't suggest trying to hack up your own scripts to do
any of this- use one of the existing tools. It's a lot more complicated
than I think you're appreciating.
Thanks,
Stephen
