The NFS client simply sees the snapshots as $HOME/.zfs/Year-Month-Day-Hour:Minute/ That's great news. In one of my Sunray installations I have a Solaris machine (currently Nevada b95) providing CDE and with all the home directories on ZFS and two Linux machines providing Gnome and KDE for ~100 users. So it should be possible for me to provide this feature for the Gnome users of Solaris *and* Linux. On the Linux side I only have to build my own nautilus with the patch <http://src.opensolaris.org/source/xref/jds/spec-files/branches/gnome-2-24/patches/nautilus-13-zfs-snapshot.diff> Sounds like an interesting project. --Meik -- Meik Hellmund Mathematisches Institut, Uni Leipzig e-mail: [email protected] http://www.math.uni-leipzig.de/~hellmund _______________________________________________ SunRay-Users mailing list [email protected] http://www.filibeto.org/mailman/listinfo/sunray-users
