Thanks. Just to make sure I understand: I can compile a stock rsync 
3.0.2 on the Linux box - no patches at all - and it will preserve all 
the Mac-specific data with -X, except for file flags and creation times? 
Is that correct?

Also: what are file flags? Stuff like access control and locked? 
Anything else?

Thanks again,
