I filed a bug that comments Wine can't create a HIDDEN file, so that Wine does not later find it with FindFirstFile().
http://bugs.winehq.com/show_bug.cgi?id=660
there was a little discussion there and I suggested a) a mode where Wine reads the special info from VFAT and NTFS filesystems. (linux kernel enhancement probably necessary)
b) for POSIX filesystems, an emulation layer where Wine emulates the attributes by storing them in a special file in each directory.
Andriy Palamarchuk commented with this:
There are plans on integration with Samba and this functionality can be implemented there for communication with Windows machines. However, I can't decide whether it is worth to implement these features for Posix file system. I suggest you to discuss the matter on wine-devel.
Is it worth it at all?
Is it worth it if I implement it as a Wine learning exercise and all you Wine demigods have to do is either say "ok" or "bad, to slow, let's ditch it" or whatever.
I don't understand that about Samba integration. Can they read the special attributes on VFAT and NTFS? Are they planning to emulate it?

I don't know to what extent others on the list have been tracking filesystem development in Linux or any other *nix, so this may be well known to some. I've been looking at it from several respects, one of which was linking ACLs to filesystem ACLs.
In the Linux area SGI's XFS filesystem already supports ACLs. Work is under way integrating this with Samba ACLs and the ext3 work being done by Andreas Grunbacher. JFS does not yet support ACLs in it's Linux incarnation but the work is on the 'todo' list. I have no knowledge of the situation wrt ReiserFS.
I mention this because part of the XFS implementation includes storage of extended attributes in a form that could be used by products such as Wine. AFAIK this does not apply to the other filesystem types although JFS with its O/S 2 background either should or should not present much difficulty to the addition.
EAs would certainly be a way of handling the 'DOS' type attributes that could not be mapped onto normal Unix attributes. Part of the work involves producing suitable utilities to correctly handle the EAs along with the files they relate to.
Clearly tying Wine in to one f/s type is not a practical option, but some work in that area by those on the periphery of the project might fill in the holes in such a way as to resolve issues on all f/s types (for Linux and other platforms).
