ACL support via NFS

[Marco De Vitis <starless@spin.it>]

Hi,
I need to copy much data from a Sarge machine to an Etch one on the same 
LAN, preserving all permissions and ACLs.
I tried using NFS, but I cannot preserve ACLs: when mounting the source 
dir on the destination machine, the destination machine does not see the 
ACLs on source files, so of course it doesn't copy them. Instead, when 
mounting the destination dir on the source machine, I get an "operation 
not supported" error on each copy (which is the same I get if I try a 
setfacl command inside the mounted dir).

Does NFS support ACLs somehow?
Do I have any alternatives, besides compressing all content and 
transferring the archives? We're talking about 200GB of data, so this 
would not be a great solution...

Thanks.
