It is now possible to have root file system on ZFS. You would still > need UFS for your /boot/ file system. Do you have a quick guide how to do this? I'm a little bit puzzled how the FS layout would look like. Just from =20 thinking about it I would do the following, but I like to know if this =20 is the right way: - ad0s1a -> contains a / with contains only the boot directory - some zpool which contains / with everything except the boot directory In one scenario I would just hope that ZFS DTRT magically, but this =20 would imply that ZFS does some kind of union/overlay/underlay mount. So I lean more towards a ad0s1a mounted by hand to somewhere else in =20 the ZFS namespace and a symlink from the zfs /boot directory to the =20 real location where the UFS is mounted. In both scenarios I'm not sure how the fstab would look like.
