There's been talk of making every transaction a snapshot. Of course, there'd be no information as to whether a transaction includes a file close, or truncation, or whatever. IMO a file versioning API would be good, but file versioning should normally be invisible, particularly to applications that are not aware of it (which would be every application to date). So think about the interfaces first. I think ls(1) would have to be made version-aware. And cp(1)/mv(1)/ln(1). That would be enough for a start. Then add find/sfind and tar/star support. And GNOME support. Nico -- _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
