Re: acl_extended_file() and NFS file systems

[James Pearson <james-p@moving-picture.com>]

I think I've worked out what is going on ... when I said the client was
a FC1 box, I didn't give all the facts - it's using a kernel based on
the FC1 kernel - actually one from ATrpms (http://atrpms.net/).

It turns out that this kernel has a 'nfsacl' patch (from 
http://acl.bestbits.at/download.html) applied that
adds CONFIG_NFS_ACL (and CONFIG_NFSD_ACL) which are enabled by default -
compiling a new kernel with the CONFIG_NFS_ACL option disabled (i.e.
something closer to a vanilla FC1 kernel), then the problem goes away ...
