Subject: bug#12523: Solaris 10 "cp -p" returns unknown error on NFSv4 share, permissions preserve not work
Date: Mon, 8 Oct 2012 13:45:08 +0200

Vendor currently investigated that problem happens with the combination of ZFS filesystem on NFSv3 only server and NFSv3 client. 

1. facl with combination of ZFS filesystem(NFSv4 acls) exported by NFSv4 server is ok
2. facl with combination of UFS filesystem(POSIX acls) exported by NFSv3 server is ok
3. facl with combination of ZFS filesystem(NFSv4 acls) exported by NFSv3 server fails on client with errno -1 which is our case
IMHO errno value in case 3 should be something useful. Like ENOTSUP.

That might work around the problem on your Solaris implementation,
but it introduces other issues, on other platforms, so I'd like
to get at the bottom of why such a change is really needed.
