All of the UFS stuff is in C, so is read-only for me. It is something I'd like to do, but it is really iffy if that can be done in time for 10.0 In general, gmirror support could be added to the ZFS section (renamed to something else). So in our current 'zfs' menu, would become the 'new partition manager' menu. Add an extra option for ZFS or UFS, and then the vdev menu would context switch between zfs vdevs and ufs options like gmirror and gstripe or something Adding an extra option for / or / /var /tmp /usr is not a bad idea either, maybe even for ZFS, offering a simpler set of datasets that might be some people's preference (especially if I can't do the following in time:) In a future revision of the zfsboot stuff, I'd like to offer a dialog where users can actually adjust the ZFS datasets. provide a menu listing the created dataset, with option to add more, and when you select a dataset, you can adjust its options or delete it (some really scary validation needs to happen here so you can't delete /usr if you have /usr/local) If the UFS stuff took the form of the current ZFS stuff (give me the entire disk, and i'll run with it), it would be fairly easy to implement, and could probably be done between 10.0-BETA1 and 10.0-BETA2 The more powerful features of the current partedit code, where it actually shows what is on your disk already, and allows you to just adjust it, and in general manage dual booting etc, that is a lot more complicated. -- Allan Jude
