The summary is: "POSIX ACLs on the server side turn (more or less) into=20 NFSv4 ACL on the client.", correct? So our current ACL based system of=20 permissions should work except that we can't modify permissions on the=20 client side until I've deployed nfs4 acl tools ... > > > > http://www.citi.umich.edu/projects/nfsv4/linux/nfs4-acl-tools/ > > > > Hmm.

Volunteers to package those things welcomed.... =2E.. which means you've possibly got your Debian packager, and I might eve= n=20 be able to do that on company time. Ok, I guess I know in which direction to put my work now, thanks a lot. =20 (nfs-iostat will be the first thing I'll try, though, to get some more=20 data.) cheers =2D- vbi =2D-=20 Why on earth should we teach children that they are not allowed to share the toys. -- Patrick Harvie, Member of the Scottish Parliament Speaking at Debconf7 --nextPart5982726.Ist6aXSyaf Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: get my key from http://fortytwo.ch/gpg/92082481 iKcEABECAGcFAkhkh7ZgGmh0dHA6Ly9mb3J0eXR3by5jaC9sZWdhbC9ncGcvZW1h aWwuMjAwMjA4MjI/dmVyc2lvbj0xLjUmbWQ1c3VtPTVkZmY4NjhkMTE4NDMyNzYw NzFiMjVlYjcwMDZkYTNlAAoJECqqZti935l6kckAnRQJrZp74o/GaWPJzH3klDMk y4xoAKCdel/2MJGK6zV4XygNVlmMdWtvPA== =PpfN -----END PGP SIGNATURE----- --nextPart5982726.Ist6aXSyaf-- --===============1348583904== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
