Hm, from my kernel config (2.6.20.1):
CONFIG_NFS_V3_ACL:
Implement the NFSv3 ACL protocol extension for manipulating POSIX
Access Control Lists. The server should also be compiled with
the NFSv3 ACL protocol extension; see the CONFIG_NFSD_V3_ACL option.
So it may work with current kernels.

You could copy the archive on the fly, like
tar cpSf - . | ssh 'cd ; tar xpSf - '
I don’t know, if tar supports ACLs.
Shade and sweet water!

Indeed, it looks active in the config for Etch's 2.6.18-4-686 kernel I'm
using. But I can't see how to make it work.

Unfortunately, it doesn't :(.
I also tried rsync, but again no ACLs were preserved.

there is star that should support ACL's with one version of the tar
format (as there are actullay severall variants of it).

Uhm, thanks I can try, although it seems to have a syntax somehow
different from tar and I'm a bit confused at the moment. I'm not sure
how can I pipe its output via ssh instead of creating a file...

Partialy! -- I have problems with NFS version 3 and it was
needed to switch to version 4 which works much better.

Why aren't you trying rsync?

Indeed, in my previous post (which still has not reached gmane) I wrote
that I tried rsync and it did not preserve ACLs... but I then looked at
the man pages and discovered that option; the problem is that it's a new
option, and the Sarge rsync does not support it :-/. It has to be
supported on both sides to work.
I'll now see if I can make it by installing the more recent rsync from
backports, it's just one version behind the Etch one.

Sigh! Also the 2.6.8 version from backports does not support ACLs.
I then built and installed 2.6.9 on Sarge from sources (although the
changelog between 2.6.8 and 2.6.9 only shows diffs regarding ACLs for
developers), and... it still does not support ACLs! Now I'm really
puzzled, as Etch has the same version and it supports ACLs.

on my sid system, /usr/share/doc/rsync/changelog.Debian.gz states
"* Now includes the ACL patch" for 2.6.9-1, so maybe it a debian
modification?

I built from the latest official stable rsync sources from the official
rsync home page, if this means "upstream".
Could I build and install the Debian Etch/Sid sources on Sarge? How
should I proceed?
Anyway, in the meantime I came up with a rather obvious solutions I wish
I had thought about hours ago: I can copy all data without ACLs via NFS
or rsync or else, and then backup the ACLs alone using getfacl and setfacl:
getfacl -R >aclbackup (on the source machine)
setfacl --restore=aclbackup (on the destination machine)

Do you have tried to backport the ORIGINAL Debian Source
2.6.9-2 to Sarge? -- I have tried it and it works.

No I didn't. Thanks for the suggestion but in the meantime I have copied
what I needed with plain cp over the default NFS and then copied over
the ACLs with getfacl/setfacl. Moreover, I later remembered that some
files also had extended attributes, so I also used getfattr/setfattr; I
believe that even the Etch rsync 2.6.9-2 does not support them so maybe
it was the only way to get around it.

Thanks, I tried it, but I got in a typical dependency nightmare: the deb
package I created this way for rsync required lsb-base version 3, while
Sarge still has v2. Somehow I couldn't install lsb-base 3, neither from
backports (only part of the v3 lsb packages appeared in aptitude), nor
from the Etch source like I did for rsync, because "Build-Depends
dependency for lsb cannot be satisfied because no available versions of
package debhelper can satisfy version requirements".
I suppose I'll have to settle with the getfacl/setfacl method...

Yes, in a recent kernel with NFS4 support and
in the mount options you must use "vers=4".
