** Description changed:
First: in my opinion this is NOT a duplicate of Bug #67175, because it
affects the NEXT long term supported ubuntu. It is both, a bug for the
former 6.06 LTS, the actual gutsy and a wishlist/bug for hardy (8.04
LTS).
- It affects both the NFSv3/v4 and the CIFS(samba) network file system
- support for ACL's of the ubuntu kernel and user tools - accordingly
- patched get/setfacl - lacking of nfs4-acl-tools, see [3].
+ It affects both the lacking NFSv3/v4 and the SMB(2)/CIFS network file
+ system support for ACL's of the ubuntu kernel and user tools. E.g.
+ accordingly patched get/setfacl, lacking of nfs4-acl-tools (see [3]) and
+ not compiled NFSv3 ACL support in the generic kernel.
I am not a kernel developer but I cannot understand where the problem
is, if major distributions (redhat/suse) seem to support nfs/cifs with
acl out of the box - for about 2 years now (2005), right when ACL
- support came for SMB (see [4] page 133). So the kernel must be major and
- the tools exist.
+ support came for SMB (see [4] page 133). So the kernel support must be
+ mature and the user tools exist.
- Because I consider this as a BUG concerning the ubuntu linux kernel
- flavour and user tools, and cannot find any comment/roadmap from the
- official side (canonical). I even don't see any effort being made on
- giving a solution to both client and server's side.
+ I consider this as a BUG concerning the "ubuntu linux kernel" flavour

I also asked for an answer here at lauchpad with Question #18907 (see
- links below [1]). Please refer this question for additional information.
- I also filed a Bug #173324 (Will nfs4-acl-tools bei in 8.04?).
+ links below [1]) and Bug #173324 (Will nfs4-acl-tools be in 8.04?).
+ Please refer this for additional information. .
Conclusion:
1. With 8.04 LTS in mind there should be a clear statement concerning
NFS/SMB(2)/CIFS + ACL support in the kernel, so customers could decide -
and ubuntu would like to address customers wishes, do they ;) One should
not be forced to recompile the kernel and loose support.
2. One also has to check/assure, that gnome, kde and xfce file managers
are supporting mounted directories via nfs/smb/cifs and handle acl's
properly.
