The people who want ZFS have in mind certain features, such as the ability to scale to very large sizes, and ease of use when administering filesystems that span multiple disks (ZFS subsumes the device-mapper/RAID layer in Solaris, so they get certain performance benefits and they are able to make it simpler to set up a filesystem that spans multiple disks with a single command --- the flip side is that they are violating an relatively well understood abstraction boundary, for better or for worse). The claimed advantages of Reiser4 don't overlap much (if at all) with the claimed advantages of ZFS. > I think for those who ask/beg Sun to release ZFS under > GPL should do the work to get ReiserFS4 to Linux! Most of the people who have been cheerleading for either ZFS or Reiser4 don't seme to have the necessary technical skills, alas. - Ted - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
