Hello Chan 
Ah, yes i see, 
rsync -XAavz --log-file /var/log/sysvol-sync.log --delete-after -f"+ */" -f"- *"  /var/lib/samba/sysvol root at server02:/var/lib/samba/  && /usr/bin/unison

This is the correct line.  ^^ 
You did add sysvol in the destination of server02 and it only need its base path. ( aka /var/lib/samba ) 
The unison config  does need /var/lib/samba 
like  : 
root = /var/lib/samba
root = root at server02:/var/lib/samba 
path = sysvol 
which make it all work. 
Can you check and test above?

Dear Louis, 

Finally I found my issue, Gentoo need to go eselest unison to choose the current running version so it will make a link on unison to that version.

However, it seem to kept creating the sysvol dir....

Rsync Command 
# rsync -XAavz --log-file /var/log/sysvol-sync.log --delete-after -f"+ */" -f"- *"  /var/lib/samba/sysvol root at server02:/var/lib/samba/sysvol && /usr/bin/unison

Hai Chan,

sorry for the late reaction, i've been ill .. still a bit..
you can safely disable : copythreshold in you config if needed.
this is only for speeding up copying of big files.
for example.
Unison internal file transfer is 5 MB/s
and the alternative copy method does : 20 MB/s

these numbers are fictional, you need to mesure that for yourself.
but for sysvol, wel.. the internal is suffician.
I have that option enabled, because of some testing with automated installations
and there are some big files in these shares.
