But the install CD can be used to create a ZFS-on-root installation (or any other disk setup you want). You just drop to the shell in the disk formatter, create the pool, create the filesystems, mount them to where the installer tells you (there's a message at the top when you drop to the shell), then exit the shell and carry on. Or something along those lines. I've never done a ZFS-on-root install; I prefer to keep the / and /usr filesystems on separate gmirror'd disks. Then put the user data (/home, /usr/local and a few other things like /usr/obj, /usr/ports) onto the storage pool. I find that setup gives your better tools for diagnosing problems with the pool and booting and whatnot. Once Boot Environment-type support is added to ZFS on FreeBSD, that may change. :) -- Freddie Cash fjwcash@gmail.com
