As an update to this I have had chance to try this and 3.1.0dev allows xattrs to be transferred very successfully between Solaris and Mac OS X, which is great from a backup point of view.

I compiled 3.1.0dev on both systems (no patches, default options - OpenIndiana 151a3 at one end and Mac OS X 10.6.8 at the other) and then did a pretty straightforward:  /usr/local/bin/rsync -ax --xattrs ... to sync a folder (with Finder colours applied) from the Mac OS X system to the Solaris system.  Did a runat/ls on the transferred folder on the Solaris side and got:

SUNWattr_ro  SUNWattr_rw

Looked good!

Did a reverse transfer and the colours came straight back up in the Finder.

Very useful feature from my point of view, we're consolidating a lot of our storage onto ZFS so being able to use rsync to backup files with xattrs without using something to convert to AppleDouble is excellent.  Thanks!  Any idea of when 3.1.0 may go stable?
