rsync -aH

Capitalization is critical here.

Option -x (do not cross devices) is not the same as -X (extendended
attributes).

I would like to know where rsync is not available.  If rsync is
available then "rsync -H" is available.

That is my concern with busybox.  They are very POSIX compliant and I'm
not sure this is a POSIX feature.  I run into this all the time in
Android and TinyCore (I've had to recode things to run under busybox ash
shell under TinyCore).  I trust rsync better than cp in differing
environments for that very reason.  I know what rsync will support (if
it's there).  I don't always know what options cp will support.

Regards,
Mike
